Thank you for coming back to me. Honestly, I have no idea when and where I installed gnuplot-tex and gnuplot-data from. This was probably years ago and I have not even used either of them for some time.
I went around the problem and installed 16.04 from scratch. Still, thanks again. --Ernst On Mon, Sep 26, 2016 at 4:32 PM, Brian Murray <[email protected]> wrote: > Where did you install gnuplot-tex and gnuplot-data from?
