Free dplot viewer 2 3 1 view and print any graph produced by dplot ball country trick

Not so much a bug but a design flaw, when opening a file if the number of points in the file exceeded the current maximum number of points, DPlot would attempt to reallocate the arrays using the required number of points and the current maximum number of curves. DPlot now does a better job of drawing grid lines on 3D plots of gridded Z values. The color key for 3D scatter plots was not displayed unless a legend was also displayed, regardless of whether Draw Color Key was checked. Several problems with color mapping on color displays have been corrected. Previous versions had a bad tendency to crash and take DPlot with it if math errors occurred overflow, underflow, division by zero, etc. The Playback feature now uses more modern settings for the Open dialog for videos.

Olympus Viewer 3 2. Save freeware Download Details. Adobe Digital Editions 4. Dia for Windows 0. Reading 4-byte unformatted data was broken with the addition of support for 8-byte unformatted data in version 2.

The Label Points command had a few quirks when working with hidden curves. List Peaks did not report the correct mean or number of points for “curves” consisting of a single point. Added a “Date separator” entry to the General Options dialog.

This entry might be important for German users or for users from any other country where the default date separator is a ‘. DPlot is a bit smarter about re-allocating arrays for unformatted data, both 4- and 8-byte files.

In previous versions when it was found that the arrays were of insufficient size, DPlot used the power of 2 greater than or equal to the required size. These points will be ignored, much as points outside the limits using the Amplitude Limits command are ignored: This results in a moderately smaller download size and a much smaller installed executable for example, dplot.

When reading ASCII text files containing multiple data sets of x,y,z points for a 3D scatter plot, DPlot crashed if the file was terminated with two or more blank lines.

With logarithmic scales, panning a zoomed plot by use of the mouse will pan the nearest number of log cycles. This is by design. Roundoff error might have caused placement of coordinate axes in XY and 1D plots to be off by 1 pixel.

The end result was that you were limited to plotting a total of data points, and you would get an Overflow error in Excel when attempting to plot more points. This has been corrected; you can now plot an arbitrarily large number of points, subject to Excel’s limitation of 64K rows.

You can now use your mouse to pick coordinates in edit mode. This feature allows you to invert the normal scaling of the axes without manually specifying the axis extents. Changes are reflected in the plot automatically rather than after you click OK.

Also added Insert , Next , and Previous buttons in addition to Delete. Tick marks with Axes Only or Box Around Plot are now drawn using the same pen width used for grid lines.

Error bar information was not correctly restored from a saved DPlot file unless the data values happened to be evenly spaced in X. FilePrint 0 equivalent to FilePrint , which prints to the default printer using the current printer settings, worked fine.

Recent change to the List Peaks menu command to display additional information might have caused memory problems seemingly unrelated to this command. In particular, saving a file after using List Peaks might have caused DPlot to crash.

Thanks to Christophe Boucher for his help in tracking down this problem. List Peaks menu command now displays mean, standard deviation, and standard error values for each curve along with the minimum and maximum amplitudes.

This was particularly a problem with users who had Excel installed but did not have Excel set as the default application to use for. Ten zoom levels are now maintained. Previous versions kept track of only 4.

It also failed to update the document caption when saving DPlot files. And it was impossible to install the Add-In on Excel 97 unless macros were enabled. These problems have been corrected in both the evaluation and licensed versions.

If you have already installed DPlot 1. This command finds all intersections between 2 curves and optionally adds data points at those intersections and labels those points. A bug in the last several versions results in incorrect placement of 2D contour plots saved or copied to the Clipboard as metafiles.

Corrected faulty advice in the setup workbook for the Excel Add-In on Excel 97; it is not possible to load the Add-In on Excel 97 or earlier versions without enabling macros.

Made a couple of small adjustments to the way a box is drawn around an XY plot. In previous versions the box was drawn completely inside the extents of the plot, which tended to obscure portions of curves in the corners and may have given the impression of faulty scaling.

The problem was particularly noticeable in metafiles. The box is now drawn with the longitudinal axis of each line segment at the respective plot extent. If you frequently plot data from Excel you should find this feature a big improvement over copying and pasting.

Added Percent number format. Added the ability to specify the number of decimal places for the default number format also used in new Percent format. There were a couple of problems associated with the recent ability to read times along with dates and currencies from text files.

Fractional seconds were discarded, and DPlot incorrectly decided that column types didn’t match from one line to the next if the time values in one line were not in the exact same character position as the time values in the previous line.

Z axis label on 3D plots used the font for the Y axis. Equation parser caused DPlot to crash in some circumstances when the equation contained extraneous spaces. Depending on the order of operations, it was possible to save an XY plot with multiple independent Y axes that you’ve zoomed in on with nonsense zoom window values for the independent Y axis.

Reading that file would then cause DPlot to crash. Recent improvements to the performance of antialiased symbols did not work on Windows 95 or If a macro resulted in DPlot crashing, the macro facility was left running in an endless loop with a tendency to hog the processor.

Though the goal is of course for no macros to cause DPlot to crash, this version of the macro facility will gracefully exit if it finds that DPlot is no longer running.

Thanks to Ray Delaforce for many of the suggestions: Selecting data points with the mouse in Edit Mode did not work particularly well with polar plots, and not at all for angles in radians rather than degrees.

Setting the angular tick mark interval on polar plots did not work properly, and it also wasn’t clear whether the input should be in degrees or radians. These controls are now disabled and hidden, with the extents of course fixed at degrees.

Scan data inappropriately limited you to scanning a in some cases small subset of your data. You can now zoom in on polar plots. In previous versions if you set the radial extents to a value smaller than the maximum radius, the plot was not clipped correctly.

This has been fixed also applies to zoom. In previous versions minor grid lines were either on or off, and if on DPlot decided on the interval. You may now specify the number of minor divisions on both axes.

These settings are also applied to tick marks as well as grid lines previously only grid lines were affected. If you have previously saved a DPlot file with the Dense grid lines option checked, the number of intermediate levels on both the X and Y axes will be set to 4.

Added Number Formats command for all 3D plots. For Powers of 10 number formatting on log scales, if Log Scale Tick Labels is set to Powers of 10 only , then the leading “1x” is omitted.

Relaxed one requirement for bar charts: In previous versions, bar charts required the same constant spacing in X for all data sets. In this version, if only one data set is used then the X values can have an arbitrary spacing.

The same requirement is still applied if multiple data sets are used. Also added a bar chart option to draw bars from the given X value to the next X, which is only meaningful in the case of non-constant spacing.

Filled areas created with Fill between curves may now include a text entry that is placed in the legend. Added a new General option to recalculate the plot extents after hiding a curve or making a previously hidden curve visible, and ignoring hidden curves in the determination of the extents.

By default the plot extents are left unchanged after hiding a curve. For example, in the “filename” c: See the description of the FileSaveAs command in the Help file for more information.

Significantly improved the performance of anti-aliased symbols, 10x or more depending on the number of identical symbols on the plot. Added a Delete button to the Insert Link dialog to help do a bit of housekeeping with the Recently used links list.

Fixed a bug that caused DPlot to crash when reading file type B if the file contained more than one data set and the data arrays were not large enough to accomodate the new data. Fixed a bug with 3D scatter plots that sometimes caused symbols to be drawn in black rather than the correct color when multiple data sets were plotted.

In recent versions DPlot balked at blank, quote-delimited columns two successive quotation marks. It also had trouble parsing quote-delimited dates if one or more spaces were included immediately after the opening quotation mark.

Filled areas created with Fill between curves were not clipped properly in metafiles after zooming in or setting the plot extents such that a portion of the fill area extended outside the plot box.

Corrected a problem with automatically-generated window captions produced by an FFT, for example. This could be accomplished in previous versions only by using user-defined constants. Thanks to Thomas Rockaway for the suggestion.

In the last few revisions, DPlot balked at blank lines in the header. Fixed a bug in text output functions. Tabs in notes or any other text that contained special control characters subscript, superscript, etc.

Waterfall plots were drawn with a semi-random base plane. Thanks to Gunnar Franke for pointing out the problem. Zooming out with data processing mode turned on sometimes gave incorrect results or caused DPlot to crash.

DPlot files saved with data processing mode on did not properly restore data processing mode when opened from Explorer as opposed to the Open command within DPlot.

Specifically, pressure and acceleration records did not cause DPlot to automatically generate integrated impulse or velocity and displacement records. DPlot failed to correctly interpret multiple column data files that contained fewer than 20 lines of data and included one of more non-data lines after the data.

Raw Data file import plugin has been amended to read if present a short header containing the number of data sets and the sampling rate for the file. You may now also enter a different default extension for these files; files with this extension will be opened by the plugin when dropped onto DPlot, and you can also associate this extension with DPlot so that double-clicking on a file with this extension in Explorer will open the file with DPlot.

Thanks to Chris Rouleau for all of the suggestions. One more hopefully the last leftover problem associated with switching from single- to double-precision data. Previously these labels were always drawn along a horizontal line extending to the right from the center of the plot, regardless of whether “0 degrees at top of plot” was checked.

By default these labels are drawn below or to the left of the radius. Added user preferences for time format on the Number Formats dialog. Added a new line style for XY plots.

Added a new Date and Time number format, which differs from Calendar Date only in that the time value will always be displayed if the time format string isn’t blank , while Calendar Date displays the time only under certain circumstances, mostly to do with the granularity of the data.

For DPlot to do anything particularly useful with these numbers requires that they be translated to the Excel date system, otherwise large gaps would exist between one hour and the next, one month and the next, etc.

Added Hexadecimal number formatting. You have a choice of 1-, 2-, or 4-byte output, as well as a choice of prefixes. Minor change to Grain Size Distribution plots now only draws the descriptive labels Cobbles, Gravel, etc.

It is now possible to have bar charts for “curves” consisting of a single point a single bar per curve. Added unit selections for Acceleration plots in Data Processing mode. Fill Between Curves functionality has been extended to allow you to fill the area between a curve and the X axis, or a curve and a horizontal line with a specified constant Y value.

In the latter case, you may also specify different colors for the areas above and below the reference line. For programmers, see the updated description of the FillBetween command.

The background of custom fill patterns is now consistent with the pre-defined patterns: Axes at 0 tick marks, labels, and line s are no longer obscured by curves or fills between curves.

Added an option to turn the radial axis labels on polar plots 90 degrees. This bug was introduced when adding the ability to use negative scale factors. Fixed a visual bug on the Number Formats dialog that may or may not have shown up on your system, mostly dependent on your screen resolution.

The result was that you would not be prompted to save these documents when closing them. Polar plots with angular measurements in degrees that had clockwise angles rather than the default counterclockwise were scaled incorrectly.

Radial axis labels on polar plots sometimes used the incorrect font. The BMP Picture file export plugin now does a much better job of preserving all colors in the picture.

In previous versions, colors set with text formatting commands and colors associated with anti-aliasing symbols as opposed to colors set explicitly in the color palette may not have been preserved in the run-length-encoded color bitmap.

This bug generally effects licensed users only, as plugins are not distributed with the evaluation version. If the file contained 20 or more lines of text preceding the data, DPlot would determine that the file contained only text and refuse to process it farther.

Spline interpolation method of Equal Intervals command was fouled up starting with version 1. The previous limit was 8. Undo files for editing data points with Edit data on 3D surface plots was broken by the addition of 3D scatter plots in v1.

Under some circumstance, “undo”ing a change in data did not correctly restore the data, and on Windows XP may have resulted in a crash. Added the option to save data from any 2D or 3D plot type as tab-separated values, in addition to comma-separated values.

As with comma-separated values, this option is only available for XY plots if all curves share the same X values and all curves have the same number of points. Each DPlot file is opened in a new document window.

Thanks to Karin Heider for the suggestion. Last update’s feature of using a negative Z scale on 3D plots to reverse the normal drawing direction has been expanded to include X and Y.

Added an option for all 3D data plots to skip 1 or more legend labels. This may be a handy feature if you like using a large number of contour intervals but don’t particularly want the legend to dominate the plot.

Equal Intervals command previously forced the start and end points of the new curve to be multiples of the interval. And a couple of roundoff problems sometimes caused the output curve to have 1 less data point than expected.

The new capabilities of interpreting CSV and other multi-column files ended up preventing at least one user from reading his standardized file formats, in that the data was preceded by several header lines consisting of a text string followed by several columns of numbers.

In previous versions, DPlot would see that the opening text string was not a number, and so decide that the data must start further down in the file. If the file contains at least 3 consecutive lines that contain the same number of columns and the same data type in each column which this user’s file format did , then DPlot decided that this must be where the data starts.

In this version, DPlot checks for 20 consecutive lines with the same number of columns and the same data type in each column. This change of course isn’t foolproof; the addition of more header lines with the same format would cause the line criteria to find a false match.

If this ends up being a problem for anyone we’ll add an input that asks the user where the data starts rather than trying to determine this automatically. Several file formats were processed using an older Windows API call that limits filenames to characters.

Several bug fixes, most associated with the 1. Smooth command for XY plots produced a botched-up curve. On some systems under some circumstances, the Contour Options command on the Options menu for 3D surface plots crashed.

FFT crashed if the number of input points was not a power of 2. New 3D scatter plots did not prevent you from attempting to read a file containing more than data sets the max and DPlot crashed if you attempted to do so.

Along with testing 3D scatter plots with a large number of data sets, it was found that a Use last-selected symbol for ALL data sets option would be handy. Interpolate command caused a crash if a curve used a long legend string an equation, for example.

BMP export licensed version only crashed if the RLE-encoded bitmap required more memory than the uncompressed bitmap. And finally, a few new useful features unrelated to bugs: This resizes a document window or the main application window such that the working area has the requested dimensions.

Internally, all data is now stored using double precision 8 byte floating point numbers rather than single precision 4 bytes. For the majority of users this change will have little effect.

But it will avoid precision problems that previous versions had when plotting large numbers with small but significant fractions. Support for CSV comma-separated values files has been greatly improved.

Your CSV files may now contain dates, times, date-time pairs, and currencies. In addition, DPlot will automatically ignore columns that aren’t interpreted as numbers or any of the other supported types without requiring the use of quotation marks.

Added Delete Thin Triangles command for random 3D data. This command is handy for cleaning up plots generated from truly random data, removing slender triangles from the edge of your surface also from any interior holes you’ve created with Delete Triangles.

Triangles with interior angles less than 5 degrees are removed if the associated triangle vertex is on a free edge. Thin triangles often do a poor job of mapping a surface.

Triangle removal is recursive: Thanks to Laurent Paris for the suggestion. For “Month” number formatting, the default tick mark interval on XY plots will be 1 1 month if the extents of the corresponding axis are more than 3 or up to 24 2 years.

If the tick mark interval is 1. For “Date” number formatting, several functions List Peaks, List Peaks in Range, Scan Points as well as the status bar readout of mouse position show the time of day along with the date.

Added “None” number formatting, which is useful for creating blank graph paper. See the modified “How do I? On 2D contour plots, if you use a custom color palette and set the color for the low and high levels to the same color, then DPlot now considers the contour values to cycle; in other words it considers the low end of the scale to be equivalent to the high end of the scale.

In this case, triangles that have all three vertices at either the high or low end of the scale will use the same solid color across the entire face of the triangle. In the case of contour lines, no lines will be drawn on this triangle.

Thanks to Bill Frenchu for the suggestion. Added Polar Plot Options menu command. It also has a switch to force polar plots to be circular, which saves you from the trouble of specifying a square width and height for the plot.

If you want elliptical polar plots, of course you may still have them. Negative angles are now allowed as input for polar plots. Zoomed views are now saved to and restored from DPlot files.

Manually-entered extents are now correctly saved to the values entered. In previous versions if you zoomed in and then saved a file, the extents were saved as the current zoomed view. Probability scales are no longer forced to be symmetrical.

DPlot now distinguishes between default input and output folders. Added “Friedlander’s Equation” to the functional forms in the “More Curve Fits” plugin distributed with the licensed version only.

This equation is generally used to fit pressure-time histories from explosive events. Print margins and orientation are now preserved from one session to the next. Margin settings may be overridden by margin settings saved in a DPlot file.

Insert Link menu command is now quite a bit more useful, and in general the functionality of linking data from other applications has been improved. The Insert Link dialog now shows recently used links, which may be selected and re-used.

There’s also a Current links list which shows all of the links for the active document and allows you to unlink data. Most importantly, DPlot now behaves correctly with multiple links in the same document.

Thanks to Raymond Delaforce for all of the suggestions. Support for unformatted binary files has been expanded to allow multiple curves in the same file. Title lines for all types of plot are now centered horizontally on the plot, not including axis labels or other objects outside the plot box.

In previous versions the title lines were centered on the output width, which led to inconsistencies between the display and metafiles. In previous versions of DPlot, the legend and notes were forced to be on the screen.

Unfortunately this led to inconsistent placement between what was seen on the screen and printed or copied to metafiles if, for example, the legend was placed well outside of the plot.

In this version the legend and notes are no longer restricted in this way, so that you should get consistent placement on all output devices. This creates a new problem, though: This command is not persistent; it only changes placement at the time you use it.

New symbol types were written incorrectly to preference files. Symbols used in the legend were clipped if the legend was placed outside the plot. Corrected bug in macro facility that prevented ForFilesIn loops from working correctly if user had Explorer’s “Hide file extensions for known file types” checked.

Equal Intervals command was not enabled properly after creating a single curve unless the curve was created by a method that by definition produced monotonically increasing X values.

Selecting a curve with only 1 point caused DPlot to crash. You were not allowed to draw a lone contour line on 2D contour plots. If you attempted to set the number of intervals to 1 programatically, or if you set the low and high contour levels to be equal, DPlot crashed.

Mouse cursor clipping was fouled up on dual monitor displays after operations that restricted cursor movement Zoom , List Peaks in Range , et. Color settings read from a preferences file were assigned to the default color palette used in new plots , rather than the currently active document.

You may now specify how many symbols are used per entry in the legend of XY plots. Previous versions always used 2 symbols. Added Arrowheads menu item to toggle the appearance of arrowheads on the coordinate axes of XY plots when Axes Only is selected.

The user-defined color palette for contour plots may now consist of from 1 to 16 colors previous versions were limited to 6 colors only. This feature will help avoid frustration for users who frequently plot very large data sets and also, on occasion, create plots with symbols.

By default, DPlot passes symbol and line types on from the first open document to all new documents. So if you work with a plot containing symbols, then create a new plot with several hundred thousand points, you can expect to wait a while as DPlot renders several hundred thousand symbols if this option is unchecked.

Added Erase group menu command for 1D plots. Thanks to Edgar Poth for the suggestion. Added toolbar button for List Peaks within a Range. Removed the “Use arrow keys to pan” message from the status bar when zooming.

This message was previously locked in for 5 seconds and was an annoyance for many users. DPlot Viewer now interprets command line parameters, so you or your end users can associate a file type with dplotvu.

Also see the Help topic for the Smooth command for an additional method of low-pass filtering your data. TextPointLabel command now allows you to rotate labels 90 degrees.

Added ContourLabelLines command to allow you to specify whether individual contour lines are labelled, the frequency of the labels, and whether the labels are transparent or opaque and drawn in black or the same color as the contour line.

Changed LineWidth command so that it may be used to set the width of the pen used to draw contour lines. Changed WindowTile command to accept a parameter that changes the window arrangement from “tall rather than wide” to “wide rather than tall”.

So you can, for example, display the X and Y coordinates corresponding to the current mouse position. The XY plot in the btest2 example program does exactly this. This prevented DPlot from running on some Windows 95 systems.

This code has been removed. Interpolation routine used by the Interpolate menu command incorrectly used linear interpolation on plots with a probability scale on the X axis. Thanks to Michael Duncan for pointing out the problem.

In previous versions it was possible to save a DPlot file that contained a curve with 0 points. This would cause DPlot to crash when the file was re-read. This situation might have occurred as the result of a macro using the SelectCurve command for which the curve index was greater than the number of curves, after which no new points were added to the new curve.

Thanks to Karin Heider for pointing out the problem. DPlot did not properly save notes that consisted of a single character. DPlot files saved while in data processing mode may or may not have had data processing mode turned on automatically when the file was re-read.

Filter command for XY plots would crash if you selected the Press notch filter with “reject frequency” set to 0. Log scale tick labels menu command was missing, and SymbolType documentation was outdated.

Color selections used in 1D plots on a color display were not used correctly. This problem was chiefly apparent with multiple open documents using different color palettes.

This allows you to specify the upper and lower limits outside which data points will be ignored. Line segments will not be drawn to or from these points. In this way you can create gaps in your curves.

This is particularly handy for plotting data with sign-changing asymptotes, like tan x. DPlot now does a much better job with clipboard metafiles in general and with enhanced metafiles containing embedded formatting codes subscript, superscript, etc.

Previous versions of DPlot always copied a standard Windows metafile to the clipboard; conversion to an enhanced metafile was left up to Windows. This left quite a bit to be desired with character placement of subscripts and superscripts.

One additional benefit of this change is that enhanced metafiles can in general be stretched or compressed within reason and all of the text entries, including the box around the legend, will be scaled correctly.

Scaling was a hit-or-miss proposition with previous versions. Contour plots now have an option to draw grid lines at the X and Y tick marks, in addition to or instead of the lines bordering the triangular mesh or rectangular grid cells.

Font colors are saved to DPlot files. In all previous versions colors were initialized to black, regardless of your previous color selections. Legend on both 2D and 3D contour plots was printed in the wrong location, depending on what the print margins were set to.

Previous change to Smooth command allowing you to smooth a subset of the data introduced a new bug that caused this command to crash in some circumstances. Thanks to Jean-Louis Oneto for pointing out the problem.

Clicking the close X button rather than the Cancel button on any of the Edit Data dialogs would cause DPlot to crash on some versions of Windows. Reallocation is handled better now, only allocating memory for however many curves are actually needed rather than preserving the previous maximum.

In previous versions, if most or all of the plot options were enabled outliers, extremes, etc. DPlot’s formatting codes for subscripts, superscripts, Greek characters, etc.

Thanks to John Spalding for the prod to get this working. Also related to 3D plots, Generate Mesh command did not properly transfer axis labels from the source plot to the generated plot.

The triangulation routine used for random 3D points attempts to create non-slender triangles, which is as it should be. But in previous versions of DPlot, units and therefore data extents were ignored.

This had the unfortunate effect of creating a plot consisting of very slender triangles if the X extents differed significantly from the Y extents. In this version, DPlot temporarily squares up the X and Y values by scaling one or the other of those coordinates, resulting in a much better contour plot for data with differing X and Y units.

Hats off to Ralph Baird for pointing out the problem. If a non-zero pen width was used for the coordinate axes, symbols lying exactly at an axis extent were not drawn.

This version takes the axis pen width into account and properly draws those symbols. If manually-entered extents were used to reverse the direction of the Y axis, the values for a second dependent Y axis were drawn incorrectly if Box Around Curves rather than Grid lines was used.

Thanks to Colin Wagoner for pointing out the problem. Also added an option to use antialiasing techniques for drawing symbols on , , and bpp displays. Added the ability to pan left, right, up and down on zoomed XY plots.

No buttons required, just use your keyboard arrow keys. This has been suggested many times in the past; thanks to Ed Quick for the prod to finally put this into action.

Added several new menu commands to specify the frequency of labels on logarithmic scales. In response to several inquiries along the lines of “How do I change the order of the legend?

Move up and Move down and a new Reorder Curves command on the View menu. For new users, the How do I? This command produces a new curve consisting of the median amplitudes of all existing curves.

Thanks to Mason Guy for the suggestion. This option might be useful if, for example, your 3D input files are ordered latitude, longitude, elevation rather than longitude, latitude, elevation.

Thanks to Risto Salo for the suggestion. Multiple column files containing X-Y data may now include a data row ID character string, specified at the time the file is opened.

Thanks to Nick Cooper for the suggestion. For unequally spaced points, the Differentiate command now uses a central difference method for calculating slope.

Previous versions used an inverse trapezoidal rule. While technically correct, this generally resulted in roundoff errors being propogated forward and giving increasingly bad results with increasing X.

Thanks to Sukhdeo Karade for the suggestion. For box-and-whisker plots and dot graphs, you may now specify the color of the line used to depict the grand mean or median. Fixed the default extents for box-and-whisker plots such that whiskers if drawn will not be clipped.

Last version’s fix to small roundoff problems did not work properly for negative values used for user-defined extents on X-Y plots. DivideCurves macro command did not work.

Thanks to Michael Sears for pointing out the problem. Zooming on XY plots with multiple Y scales sometimes produced illogical extents on the second Y axis. Labels for multiple Y axes with a probability scale on X and linear scale on Y were incorrect.

Thanks to Kirt Harle for pointing out the problem. Several problems with color mapping on color displays have been corrected. These problems were a byproduct of a fairly recent change allowing unique color palettes for each open document.

Added file import plugin to read raw data files consisting of 8-, , or bit signed or unsigned data, with either Intel or Motorola byte order. The parser also failed to trap the error of raising zero to a negative power.

Probability scales on the X axis bombed for X values outside the range 0. In this version the X axis is treated identically to the Y axis: Small roundoff errors when using user-defined extents might have caused incorrect extents to be used.

Added Combine Curves command to the Edit menu. This allows you to append the data values from one curve to another curve. Equation parser did not correctly interpret numbers using scientific notation i.

In most cases this resulted in the number being interpreted as 0. Previous versions were prone to shift labels around in an effort to ensure good arrow placement.

In this version, labels stay where you put them and the arrow anchor point will shift to one of the 4 sides of the label as needed. Added a setting to draw labels turned 90 degrees.

And last, you may now include up to 50 labels in a single plot previous limit was Both major and minor grid lines on XY plots may now be drawn with a line style other than solid lines. Also added missing support for Dense Grid Lines setting to polar plots.

Added Powers of 10 number formatting. This is a nice enhancement over scientific notation e. The corresponding EditSmooth macro command has likewise been modified. Thierry Picornell for the suggestion.

Corrected placement of Y and Z axis labels on triangle plots for output to metafiles. Depending on the version of Windows in use, DPlot would either crash or produce a bogus error message when reading.

CSV files containing X,Y,Z points file type K if the file contained one or more extra blank lines at the end of the file. The majority of users who read this will scratch their heads and wonder what the point of this is.

If, on the other hand, you spend hour after hour analyzing video footage and megabyte upon megabyte of data recorder output from high-speed events things that go BOOM , for example , you’ll most likely find this addition to be very, very, Thanks to David McDaniel for pointing out the oversight.

This change will not break existing plugins or applications sending data to DPlot. The picture is not preserved in any way, so that if it is covered by another window it is then basically gone for good.

You may, however, be able to think of several applications where this behavior might be useful. To keep the picture, you need It is the calling application’s responsibility to then draw the bitmap and delete it when it is no longer needed.

DPlot will be closed before the function returns, unless it was already running. This function will also tell you whether DPlot was already running when called, so that you don’t annoy the user by closing DPlot when the user didn’t want it closed.

Whoops New More Curve Fits plugin released yesterday retained debugging code that would cause the plugin to crash on all systems other than the author’s. Very sorry for the inconvenience.

Baseline Shift plugin did not properly catch the case of the detected arrival time occurring at the first data point in the input. This caused a divide by zero error and Notes did not work properly with metafiles copied to the Clipboard on Windows and XP.

One other strange aspect of metafiles that has also been fixed: Office products displayed black grid lines unless the grid line width was greater than 1 pixel, though the Windows ClipBook Viewer displayed the correct color.

File Append with DPlot files did not work properly unless the maximum array sizes were already set to values large enough to accommodate the new file. Not so much a bug but a design flaw, when opening a file if the number of points in the file exceeded the current maximum number of points, DPlot would attempt to reallocate the arrays using the required number of points and the current maximum number of curves.

So if, for example, you had arrays allocated for a maximum of curves and attempted to open a file containing 1 million points, DPlot would attempt to allocate arrays for million points. Formatting options have been expanded to include percentage labels instead of or in addition to amplitude labels.

Labels may now be placed above bars. Previous version always drew labels just inside the top of the bar, and bars shorter than the label text did not include the label. Last accepted bar chart options are preserved from session to session and are now the default options for any new bar charts.

Bar charts may now include error bars. For best results turn off all labels and use side-by-side rather than stacked bars with multiple data sets. Histograms will copy both the 1st and 2nd title line if one exists from the source plot.

Previous versions copied the 1st title line only. Curvefit plugin licensed version only: Added one new equation form: Improved determination of default initial coefficients for several equation forms.

Added a max iterations entry that might be useful for the exponential forms that tend to converge slowly. The plugin now takes a bit of preemptive action in forcing coefficients to legal values in the case of the exponential forms.

This change allows a poor initial fit to find a better solution without blowing up with an overflow error. For XY plots you may also optionally label the point using this tool.

For the licensed version only, improved initial estimates for the coefficients in an exponential curve fit. Previous versions worked well for more-or-less noiseless input, but not well at all with a lot of scatter.

Added the ability to import macros from disk. Previous versions placed tick marks at equal intervals equal number of days. Custom colors used in contour plots may now be saved and re-opened on the Contour Plot Colors dialog.

Also added color picker controls for each of the six colors. Previous versions required you to enter explicit r,g,b values for each color. Thanks to Ukuleles by Kawika’s David Hurd for the suggestion.

DPlot now does a much better job of picking an initial number of contour intervals. Default contour values will now be some multiple of 1, 1. Added ability to label contour lines on the plot, rather than restricting you to using the legend.

You control whether the labels are transparent or opaque, same color as the corresponding line or black, and the frequency of the labels. This feature will no doubt be tweaked a bit; if you try it and have a suggestion, of course let us know.

Added OperateX , OperateY , and OperateZ macro commands, corresponding to the new menu commands that allow you to manipulate plot coordinates with an equation.

If you either zoomed in or forced the extents of a 2D plot of contour lines, saved metafiles did not properly draw the contour lines. You may now control the line weight of contour lines on 2D contour plots.

Previous versions fixed the line weight at 1 pixel for display monitors and bitmaps and 0. Thanks to Herb Sorensen for the suggestion. Thanks to Dimitris Evangelinos of the Aristotle University of Thessaloniki for this and the following suggestion.

Multiple column input files type D on the Select File Type dialog may now contain non-numeric columns within the data, as long as those columns are “surrounded by quotation marks”. DPlot will ignore non-numeric columns, other than to display them on the Specify Columns to Plot dialog.

Function parsing routine now accepts log10 in addition to logh for base 10 logarithms. Saved metafiles both enhanced and standard Windows for 2D contour plots did not use the correct font for numbers along the X and Y axes, and included much more white space than necessary.

Attempting to perform this operation resulted in a crash. In previous versions if you turned on Data processing mode when more than two curves were present, then later used Undo to turn data processing mode off, DPlot crashed.

Negative values on stacked bar charts were not drawn as most would expect, which is to say they were inconsistent with how Microsoft Excel draws them. New bar labelling feature did not work at all with negative values.

DPlot now traps underflow errors on input and truncates offending numbers to 0. In previous versions, it was possible to read a file or paste data from the clipboard that contained values with magnitudes less than 1.

This behavior could eventually cause a crash, usually when writing a file to disk. Thanks to James Drake for pointing out the problem. The last several versions failed to detect any of the data recorder file formats when a file of that format was dropped onto DPlot’s window.

This version should successfully identify any of the supported data recorder file formats without user intervention. Moved bar chart formatting options from the main menu to a separate dialog and added Bar amplitude labels option.

If checked, labels showing the height of each bar are drawn near the top of the bar. BarChartStyle macro command has been expanded to include flags for stacked bars and bar labels.

Added GenerateMesh macro command to produce a rectangular grid of 3D points from a triangular grid of random 3D points. Several commands on the Edit menu for XY plots now allow you to select multiple curves to operate on.

Previous versions allowed you to operate on all curves or one curve only. Thanks to Susan Blouin for the suggestion. Added RunPlugin macro command, which allows you to run any of the Generate menu’s plugin modules from within a macro or from another program.

Custom line drawing routine used for XY plots with patterned line styles did not properly handle again densely-spaced data points. Hopefully this version represents the final fix to this problem.
