This is a bug in that matplotlib is not reading the preferred encoding correctly, because doing so has undesired side effects in some cases. An easy workaround is to add the following to the top of your script (before importing matplotlib):
import locale locale.setlocale(locale.LC_ALL, '') Note, you will also need to select a font that has Cyrillic characters. The default font shipped with matplotlib "Vera Sans" does not, but you can use its more-Unicode-complete sibling "DejaVu Sans" (installed on most Linux systems by default). Interestingly, another use had a similar problem quite recently. The following branch of matplotlib may also fix your problem: https://github.com/mdboom/matplotlib/tree/locale_formatting To test this, you would need to build it from source, and then set the rcParam "axes.formatter.use_locale" to True.
