I am trying to recreate this TikZ picture I saw https://tex.stackexchange.com/a/212936 (specifically the last image)

However upon compiling I get a message saying that the process exited ith errors but there is no information in the log file (see attached screenshot)

I am not sure why this error as occurs as I can render both examples from: enter link description here

My code I am trying to render:

Upon inspection of the log file I found this near runsystem

  • I get no error. Did you run LaTeX with -shell-escape? – egreg Jan 7 at 11:56
  • I'm curious, what part of this code needs gnuplot (I'm guessing it is hidden somewhere) – daleif Jan 7 at 12:00
  • yes the wave plot part – sab hoque Jan 7 at 12:05

    If your on windows try my mwe here tex.stackexchange.com/questions/456297/… I will show some basic checks in a rudimentary Results.txt file – user170109 Jan 7 at 12:46

    Ok I updated gnuplot to 5.3 (todays version) and get several warning etc but not from gnuplot the issue in my case seems to be font related as I have had problems with garamond in the past (I probably need to clear out a local file) so if I change Garamond to the one I have available [ebgaramond] it compiles for me (with an acceptable pair of font warnings) – user170109 Jan 7 at 14:18

This appears to be a font issue as {mathdesign} requires at least three specific fonts to be available, however only one at a time so if you cut and paste these uncomment your one of choice


Used with the fontenc package \usepackage[T1]{fontenc}

The font names may be abbreviated i.e


ensure your font mapping is updated via TeX Live manager or MiKTeX-console. Having personally had problems with Garamond in the past it works in my case if I change it to


If that does not work consider reloading the mathdesign package (or simply commenting it out)
