DPlot

[DPlotAdmin]

Beta releases of DPlot and DPlot Jr are available. You must already be running DPlot 1.9.9 or DPlot Jr 1.9.9 to use this release. To check the version number of you are currently running, select "About DPlot" on the Help menu. If you are not using version 1.9.9, you can get the trial version of DPlot from the Downloads page. Licensed users should instead use the link provided to the mailing list. For DPlot Jr, get the setup program from http://www.dplot.com/dplotjr_setup.exe.

To use this release, right-click on [Edit: link to beta version removed] for the full version or [Edit: ditto] for DPlot Jr and select "Save Target As". Save this file to the folder where you installed DPlot or DPlot Jr (default=c:\Program Files\DPlot|Jr|), overwriting the previous version.

Changes:

• Added right-click menues for setting the number formats used on the coordinate axes. Click on any number to bring up a list of available formats.
  
  
• Added accelerators (shortcut keys) for the text attribute buttons for the titles and axis labels, text notations, legend, fill regions, etc.
  
  Edit: These are documented in the Help file, but... you don't have that . The shortcut keys are:
  Subscript: CTRL+down arrow
  Superscript: CTRL+up arrow
  Symbol: CTRL+s
  Bold: CTRL+b
  Italic: CTRL+i
  Underline: CTRL+u
  Double size: CTRL+2
  Color: CTRL+k
  
  
• Changed the behavior of right-click menu when you click within the graph area of an XY plot. Previous versions showed the Edit menu, which was not especially useful. This version shows scale types (Linear X Linear Y, etc.) and any options specific to that scale type.
  
  
• Bug fix: If you used "Specify extents" with a polar plot and subsequently switched to any other scale type, DPlot crashed. This was due to the low and high extents being set internally to meaningless numbers that were ignored for polar plots. An aesthetic, related change: if a polar plot had angular values in degrees (rather than the default radians) and tick mark intervals were manually set, when switching to a different scale type you'd generally get many more tick marks than intended, since the interval is stored internally in units of radians. In this version the tick mark interval is multiplied by 180/PI when switching from polar plots to another scale. The reverse operation is performed when switching back to a polar plot.
  
  
• Bug fix: One more glitch with printing surface plots with shaded bands has been fixed. In the previous 3 releases if you did not have Specify size and WYWISYG on the Extents/Tick Marks/Size> dialog checked, the fonts used in the plot were a very large scale and resulted in overlapping text and not much else. In this version if Specify size is not checked, the plot will be scaled to an 8 inch x 8 inch box, and scaled down if necessary to fit the page margins. To ensure that the printout resembles the plot you see on the display, though, it has always been and will always be best to check the Specify size and WYSIWYG boxes.
  
  
• Bug fix (affecting programmers only): Scaling information returned by DPlot_GetBitmapEx was incorrect for 3D views of 3D data if the legend was shown on a plot. This made it impossible to correctly project and add your own graphic objects to DPlot-produced bitmaps at the correct location. Next release of DPLOTLIB will include examples showing the addition of graphic objects by another program. For 2D projections this is trivial and can be figured out from the mouse movement code in the examples. For 3D projections it is a bit more complicated. If you have a pressing need for this sort of functionality in your own program let me know and I'll send an example before the next release.
  
  
• Bug fix: $STDEV text shortcut displayed the result using standard C runtime function, while most other shortcuts used DPlot's internal number formatting routine. This is primarily of importance to users who use a comma for a decimal point.
  
  
• Bug fix: It was all but impossible to add or edit more than one point label for 3D plots due to a bug with updating the dialog when selecting a different label. Thanks to Steven Dixon for pointing out the problem.
