Dear all,

The following TeX expression did not produce any error message with matplotlib versions 0.87.3 - 0.90.2 :

r'$Wavenumber,\ [\ cm^{-1}\ ]$'

The following error is produced with version 0.91.2 :

<class 'matplotlib.pyparsing.ParseFatalException'>: Expected end of math '$'

$Wavenumber,\ [\ cm^{-1}\ ]$ (at char 0), (line:1, col:1)

The problem comes about because of the square brackets. Could everyone please explain me how to handle this situation (without placing the brackets outside of '$$') ?

Thanks in advance,

Dr. Maxim Fedorovsky.

It's a bug in 0.91.2. This has been fixed on the maintenance branch (if you're comfortable using SVN), or we do plan to release a bugfix 0.91.3 release soon.

Cheers,

Mike

Thanks a lot for the help) I have noticed that \angstrom is not anymore supported in 0.91.

With best regards,

Maxim Fedorovsky.

You can use \AA for angstrom (to conform to the (La)TeX standard).

Cheers,
