Does anyone have software for extracting x-y coordinates from
a graph (log-log, log-linear, etc.).  We have PENWORKS with a Kurta
tablet but it doesn't come with software that will allow you to
specify the x,y axis (log or linear), origin, and xmax, ymax, and
then write the data to a file.  As far as I can figure out, PENWORKS is
just a driver to use the tablet in applications like MacDraw.
I was hoping there would already be some public domain software
since I am sure others have wanted to do the same thing.
