May I suggest some free (as in freedom) plotting software such as SciDAVis...
Indeed, my lab used to be locked in certain age-old proprietary (and also closed-source) junk software in order to do certain dirty jobs ("thanks to" the secret proprietary data file structure and format).
What I am doing is to completely redirect those old junks to /dev/null, by guiding the (collaborating) professors and post-graduate students (Ph.D. and M.S. candidates) to study and use exclusively free (as in freedom) software. Some of my Ph.D. students are fairly good at some of them.
Now my lab uses (but not limited to) the following free/libre software: LibreOffice GNU Octave SciDAVis Dia Inkscape
