This is a very flexible plotting program, with regard
to sizing, fonts, etc. Comments and arrows can be put anywhere on the graph. The
appearance and spacing of the gridlines are adjustable. The user can enter an equation or
import ASCII or spreadsheet data. By printing to file as a *.WMF file, the graph can be
embedded into an EXP document and cropped, sized, etc. Lately, I have used CoPlot also to
create curves without an axes or other labeling and importing their *.WMF files into
Canvas to get realistic examples of signals, random processes, etc.
CoPlot is a DOS-based plotting program with good
output, but a clunky interface. It's greatest strength is that it is relatively bug-free.
It can also produce a wide variety of plot types.
