Re: Possible problem with CGM terminal

Ethan,

That is great news.  You are a genius!

I'm in the middle of upgrading our engineering modeling software from Gnuplot 3.8h to a CVS snapshot.  We generate about 15 different kinds of plots (2D, 3D and pm3d) and support screen (X11 & Windows), Postscript and CGM output types.  We needed to add PNG file type support so I decided to upgrade Gnuplot at the same time.  Everything has been pretty smooth.  Some of the labeling for the screen plots had to be adjusted now that X11 supports rotated text.  For my newest plot type, the macros and string variables are indispensable.

Thanks again,

Mike Sutton
