Beta version is available at http://www.dplot.com/beta/dplotsetup.exe. [Edit: Link changed to standard download, which now includes all changed mentioned below.] Licensed users must have version 1.9 or later installed before installing this version. If you're a licensed user not on the mailing list, contact me for instructions in getting version 1.9.1 before installing this beta.
Changes:
Added an input for the bar width on bar charts/histograms. By default in previous versions, bars butted up against each other (100% width). Default width is now 100% for generated histograms and 75% for all other bar charts, and may be controlled with Options>Linear/Log Scaling>Bar Chart Options.
It is now possible to have bar charts for "curves" consisting of a single point (a single bar) per curve.
Fixed a visual bug on the Number Formats dialog that may or may not have shown up on your system, mostly dependent on your screen resolution.
Added unit selections for Acceleration plots in Data Processing mode.
