Due to recent technical problems and changes in policy on SourceForge, we have decided to move the matplotlib mailing lists to python.org. To subscribe to the new mailing lists, please visit: * For user questions and support: https://mail.python.org/mailman/listinfo/matplotlib-users mat...@py... * For low-volume announcements about matplotlib releases and related events and software: https://mail.python.org/mailman/listinfo/matplotlib-announce mat...@py... * For developer discussion: https://mail.python.org/mailman/listinfo/matplotlib-devel mat...@py... The old list will remain active in the meantime, but all new posts will auto-reply with the location of the new mailing lists. The old mailing list archives will remain available. Thanks to Ralf Hildebrandt at python.org for making this possible. Cheers, Michael Droettboom
