DPlot graphs and manipulates 2D and 3D data from a variety of sources in many different formats. While designed for scientists, engineers, and other technical fields, DPlot's straightforward interface will appeal to anybody interested in creating presentation-quality X-Y plots and/or contour plots of 3D data.
- 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)
- Made a change to the drawing order for XY plots when minor grid lines are used and the minor grid line color is different than the major grid line color: In previous versions the minor grid lines for the Y axis would overlay the major grid lines for the X axis. This was only noticeable when the minor grid lines used a different color than the major grid lines. In this version minor grid lines will not obscure major grid lines
- If multiple Y axes were used, the title for the 2nd Y axis was placed far right enough that it was impossible to overlap any numbers (or dates, etc.) on the X axis. So for dates/times on X, for example, the 2nd Y axis title was positioned much farther to the right than it would be for the default number format. The intent was probably good at one time, but since this same check isn't performed for the primary Y axis it was, at best, overkill
- Bug fix: If "Axes at 0" was checked and grid lines were used on the Y axis, the bottom of the plot would be drawn (actually overdrawn) with the grid line color. This was particularly noticeable if the axes line width was the same as or smaller than the grid line width and used a different color
