DPlot full changelog
DPlot 2.3.5.7
released Apr 18, 2017 (New Release)
Bug fix: Gave up on trying to verify DPlot's own digital signature with new, more secure sha256 algorithm. Attempting to verify the signature under both Windows Vista and Windows XP resulted in errors that erroneously indicated the file had been tampered with.
DPlot 2.3.3.8
released May 20, 2013 (New Release)
· Added Open-High-Low-Close (OHLC) chart option. This is primarily useful for those tracking stock prices.
· Added X=f(T), Y=g(T), Z=h(T) command on the Generate menu, which allows you to generate points in a 3D scatter plot with X, Y, and Z all a user-defined function of a fourth independent parameter T.
· Added entries for the SAE J211 CFC filters to the Filter command on the Edit menu. This is mostly a matter of convenience to those who crash cars for a living: the filter coefficents are defined here.
· Modified the MultipleXAxes and MultipleYAxes commands so that they will accept an equation as input.
· Extents for scales using quot;Calendar Datequot; number formatting are now rounded to the nearest integer (nearest day). Though technically correct before, previous versions were visually confusing if, for example, the low extent was at some time other than midnight since the time was not shown.
· The setup program now copies examples.xls to the DPlot folder below your quot;My Documentsquot; folder

DPlot 2.3.2.3
released Apr 10, 2012 (New Release)
· Added a quot;Hidequot; option for individual reference lines.
· For licensed users only, added a file import plugin for Pacific Instruments BEU files.
· quot;List Peaks in Rangequot; 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.

DPlot 2.3.1.6
released Jul 19, 2011 (New Release)
· Bug fix: The quot;List Peaks within a Rangequot; 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.

DPlot 2.3.1.1
released Jun 1, 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 quot;List Peaks Within a Rangequot; 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.
· For file type D (multiple column text files, XY data) added a Heading rows have prefix entry to the Open dialog box.

DPlot 2.2.8.5
released Apr 26, 2010 (New Release)
· Added the ability to specify a background image
· GPS-recording with a background image taken from Google Earth
· for 2D graphs (with the exception of polar charts and triangle plots). Added corresponding SetBackgroundImage macro/DDE command.
· Added Normalize command to the Edit menu for XY plots, along with corresponding EditNormalize macro/DDE command. This command scales the Y values to 0-1 or 0-100.
· Added a right-click menu option for XY plots to quot;Add $X, $Y Labelquot;, which saves a bit of effort over using Edit mode and/or the Label Points command on the Text menu. Labels produced with this command will be framed and opaque. As with all other labels, attributes can be changed with the right-click menu or by double-clicking on the label.
· Added right-click menu options for the legend (in XY plots) and text notations to change the anchor point of those objects.

DPlot 2.2.8.3
released Mar 16, 2010 (New Release)
# Bug fix: Aaarrgghhh. One more fix associated with quot;betterquot; handling of blank columns in CSV and other text files that started in version 2.2.8.1. If you had two or more columns and the data was preceded by a line containing one or more numbers (not necessarily associated with the data but which might have been, for example, the number of following data rows) then DPlot would initially interpret that number as part of the data, but then fail to properly read the file.
# Bug fix: Previous versions saved the axis associations of only the first 20 curves to preference files (File>Save Preferences).
