The DOS Versions of CoPlot, CoDraw, CoStat, and CoVis are DOS graphics and statistics programs that can also be used in a DOS window in Windows 3.1/95/98/Me/NT/2000/XP or OS/2.
Note that the new CoPlot 6.3
has all of the features of all of these DOS programs
but is a modern GUI program that runs natively on
Windows 95/98/Me/NT/2000/XP, Linux, Unix, Mac,
and other operating systems.
CoPlot 6.3 does not run on DOS or Windows 3.1.
