Set mathtext font (computer modern, latex)

ParaView Support
1

I would like to use the Computer Modern (cm) font in Paraview for Latex math rendering, but this solution, i.e. editing the matplotlibrc file, does not work for me.

Troubleshooting:

  • edit C:\Users\user\.matplotlib\matplotlibrc and C:\Program Files\ParaView 5.13.1\bin\Lib\site-packages\matplotlib\mpl-data\matplotlibrc
  • add mathtext.fontset: cm and mathtext.rm: serif (the rest remains unchanged)
  • in Paraview, add Programmable Source and run
import matplotlib as mpl
print(mpl.get_configdir())
print(mpl.rcParams["mathtext.fontset"])
print(mpl.rcParamsOrig["mathtext.fontset"])
print(mpl.rcParams["mathtext.rm"])
  • this confirms the changes and prints C:\Users\user\.matplotlib, cm, cm, serif
  • add Text Source with $\mathrm{Text}$ $\phi$, which produces the following output
    grafik
  • for reference, this is expected
    grafik
  • re-running the Programmable Source now outputs C:\Users\user\.matplotlib, dejavusans, cm, serif

This suggests to me, that Paraview sets the mathtext font to Dejavu Sans somewhere during the text rendering process.

I’m on Windows 11 with Paraview 5.13.1
