Latest beta version of DPlot is available here: http://www.dplot.com/beta/dplotbeta.exe. And there are corresponding versions of
DPlot Jr: http://www.dplot.com/beta/dplotjrbeta.exe
and DPlot Viewer: http://www.dplot.com/beta/dplotvubeta.exe

Edit: Links changed to standard versions, which now include all changes mentioned below.

Changes (including last 2 beta versions):

  • All 3 executables in this distribution are compressed using ASPACK (http://www.aspack.com/). This results in a moderately smaller download size and a much smaller installed executable (for example, dplot.exe goes from 3222Kb to 654Kb). I was a bit concerned that decompression would cause a noticeable delay or, worse, that this would foul up starting up DPlot or DPlot Jr and sending data via DDE/DPLOTLIB. But in testing so far, there's no discernible startup delay and all test programs work as expected. If you do experience any sort of problems, of course let me know. Thanks to Chris Brown (http://code-breaker.com/) for the suggestion.
  • Added a correction to the Excel AddIn installation for non-English versions of Excel 97 and earlier versions. Other than network installation problems the AddIn installation should now work for everybody regardless of Excel version or Windows version. But of course if you have any problems I'd appreciate hearing about them.
  • You can produce an XY plot from a 3D surface plot that is the intersection of a vertical plane with the 3D surface. See Generate>XY Plot from 3D Surface and/or the corresponding XYZ_to_XY menu/DDE command.
  • DPlot now does a better job of drawing grid lines on 3D plots of gridded Z values. Previous versions had a few problems with drawing order and roundoff errors, causing gaps in grid lines.
  • Title lines and axis labels may now use multiple lines. You can add a line break to these entries by embedding a "\n" sequence (the actual characters \n, not a linefeed character) in the string.
  • Added Reference lines menu command and corresponding RefLine and DeleteRefLine macro/DDE commands. This allows you to quickly add horizontal or vertical lines to XY plots at a user-specified X or Y value without going to the trouble of creating a new "curve".
  • Changed Hide all curves but... command on the View menu to Hide curves and made it obvious which curves are already hidden by including checkmarks in the curve list.
  • On XY plots, you may now have 0 data values and still use a log scale. These points will be ignored, much as points outside the limits using the Amplitude Limits command are ignored: If point N-1 is positive, point N is 0, and point N+1 is positive, you will not get a line segment drawn between point N-1 and N+1.
  • Bug fix: 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.
  • Bug fix: Choosing to display a plot's filename by use of the Print Caption menu command or ShowCaption macro/DDE command was not properly saved to a DPlot file.
  • Bug fix: With logarithmic scales, panning a zoomed plot by use of the mouse will pan the nearest number of log cycles. This is by design. However, if you drag less than 1/2 log cycle then the arrow associated with dragging remained on the plot.
  • Bug fix: DPlot Jr's File Format dialog used by the Save As... command has been fouled up for several versions, having not kept up with the full version's inclusion of Tab-separated values as an output option.

Shocked Ack! An old error with the Erase Curve menu command for XY plots has been found and fixed. Deleting multiple curves worked correctly only if those curves happened to be at the end of the list of curves. Thanks to Bob Britt for pointing out the problem. The file locations are the same:

DPlot Jr: http://www.dplot.com/beta/dplotjrbeta.exe
