| Version | Date Released | Status | Release Notes |
| 2.3.2.3 | Apr 10, 2012 | New Release | · Added a "Hide" option for individual reference lines. · For licensed users only, added a file import plugin for Pacific Instruments BEU files. · "List Peaks in Range" now works with 2D views of 3D and 4D surface plots, in addition to XY plots. · Modified the Polynomial Curve Fit and Histogram menu commands to ignore points with Y values outside the limits set with Amplitude Limits. · Applied the same Amplitude Limits change to all Generate menu plugins that produce new data in the same plot (as opposed to replacing existing data or creating a new document). (For plugin authors, you must use version 4 of the plugin interface to take advantage of this change. Contact us if you have any questions about this.) · For Generate menu plugins that produce a new document, all points are preserved but the Amplitude Limits settings, if any, are now applied to the new document. |
| 2.3.1.8 | Aug 9, 2011 | New Release | · Bug fix: The "fix" for Time of day (fractional days) number format in 2.3.1.7 unfortunately broke all other formats on the Extents/Intervals/Size dialog. |
| 2.3.1.6 | Jul 19, 2011 | New Release | · Bug fix: The "List Peaks within a Range" command contained a bug that might have caused DPlot to crash since the inclusion of the median calculation. · Bug fix: Bar charts with the bar width 1 pixel wide (which might happen if you have more bars than pixels in your screen resolution) were not drawn for filled bars unless the bars were outlined. · Modified LineType command so that it does not complain if the curve index is less than or equal to 100. In previous versions the LineType command complained if the curve index was greater than the currently-allocated number of curves. |
| 2.3.1.4 | Jul 6, 2011 | New Release | · Bug fix: For 2D contour plots of random 3D data, if you unchecked "Label every major line" then an uninitialized data problem might have caused a crash. · Bug fix: If multiple XY curves existed and you deleted any curves other than the last, DPlot might have fouled up curve associations, e.g. a point label previously associated with curve 5 might now be associated with curve 4. · Bug fix: With a negative tick mark interval (decreasing values from left-to-right or bottom-to-top) DPlot might have displayed 0 as some very small number, e.g. 2.2546E-16. |
| 2.3.1.1 | May 31, 2011 | New Release | · Modified Average All Curves and Median of All Curves commands to only operate on visible (as opposed to hidden) curves. · Added the complementary error function ERFC to the functions available with Y=f(X) and similar commands. The complementary error function is defined as erfc(x)=1 - erf(x). · The List Peaks command now includes median, skewness, and kurtosis values (for Y in XY plots, Z in 3D plots, amplitude in 4D plots). Median, skewness, and kurtosis are also output for "List Peaks Within a Range" on XY plots. Also for the latter command, added a bit of slop so that plot extents would be included in the desired extents. In previous versions in most cases the low or high extents would not be exactly equal to the corresponding plot extents, due to roundoff error in converting mouse coordinates to plot coordinates. |
| 2.3.1.0 | Apr 12, 2011 | New Release | · Bug fix: If Print Caption on the Text menu for 1D plots was checked, plots copied to the clipboard might have had the filename overlapping the labels on the horizontal axis. · Bug fix: If you dragged-and-dropped a text file with multiple columns of numbers onto DPlot and Pick Columns to Plot was not the default setting, DPlot saw the first column as Y values with X starting at 0 and incremented by 1, rather than the more usual X in the first column. |
| 2.3.0.8 | Mar 7, 2011 | New Release | · Line breaks are now supported for point labels. · Added Rank plugin to the Generate menu. This feature is roughly equivalent to Excel's PERCENTRANK function. · Added Average Curve with Error Bars plugin to the Generate menu. This plugin produces a new document with Y equal to the mean of all Y values at any X within a user-specified interval, and error bar extents equal to a) the mean + the extreme values, b) the standard error in the Y values, or c) the standard deviation in the Y values. · Added a Disable hide/unhide with middle mouse button option to the General Options screen for those users who tend to inadvertently click the mouse wheel. · Made several improvements to the "Multiple Plots" dialog for printing multiple documents. Documents are now shown in a list box with more room for the document title than the previous collection of 32 checkboxes. Corrected an aspect ratio problem in the layout diagram that might have resulted in a fouled up picture for landscape orientation. |
| 2.3.0.7 | Feb 8, 2011 | New Release | · Expanded on the last update's new feature of hiding a curve with the middle mouse button: If you press CTRL + middle mouse button while pointing to a curve, all curves except the one pointed to will be hidden. · Fixed an annoyance with inserting Symbol characters in text strings. In previous versions the insertion point was placed before the newly-inserted Symbol character(s). In this release the insertion point follows the new characters. · Bug fix: The Reorder Curves command did not mark a file as "dirty", prompting you to save before closing. · Bug fix: DPlot crashed with an overflow error for Y values with amplitudes greater than about 1.34E+154. The error occurred in squaring the amplitude as part of finding the RMS value. (The maximum amplitude that DPlot can handle is the maximum amplitude of an 8-byte floating point number: 2^1024 or about 1.798E+308. In other cases DPlot gracefully balks at numbers exceeding that limit, and now does for RMS.) |
| 2.3.0.6 | Jan 25, 2011 | New Release | · When zooming with the mouse wheel, you may now restrict zooming to the X direction by pressing the CTRL key, or to the Y direction by pressing the SHIFT key. · For XY plots you may now hide a curve by pointing to it and clicking the middle mouse button (mouse wheel on the majority of mice). If the middle mouse button is clicked when the mouse does not point to a curve, all curves are made visible. · Modified "Make Step Plot" plugin (licensed version only) to include an option to center the steps on the input X values. Thanks to Dr. Ian Crawford for the suggestion. · Improved performance of antialiasing. In all previous versions the antialiasing performed for line segments by DPlot was very inefficient with all or portions of line segments that were outside the plot limits (after zooming, for example). |
| 2.3.0.5 | Jan 10, 2011 | New Release | · Added options for image export. For GIF and PNG images, you can now specify that the plot background color should be transparent. (Whether the target application respects the transparency setting is outside DPlot's control. Google Earth, for one, does honor this setting.) For both GIF and PNG images, antialiasing is forced off and the standard Windows' font antialiasing is turned off. You may get better results saving to 32-bit PNG, particularly when importing images into Google Earth. Updated the SetPluginImageDims macro/DDE command to take account of this new capability. |
