I've set the fonts to use (via font.serif, font.sans-serif, etc) and the font family (via font.family), and the size (via font.size), but commenting those out doesn't seem to help. The system-installed fonts all should have the minus sign, though I don't know for sure which fonts matplotlib is using. joey ------------------------------------------------------------------------------ Virtualization is moving to the mainstream and overtaking non-virtualized environment for deploying applications. Does it make network security easier or more difficult to achieve? Read this whitepaper to separate the two and get a better understanding. http://p.sf.net/sfu/hp-phase2-d2d _______________________________________________ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
