Hello everyone! Just got an answer from the matplotlib list and it works!

However, sage uses the matplotlibrc from my myhome/.matplotlibrc but than it can't find my Qt4Agg (no problem only using python). ImportError: Qt4 backend requires that PyQt4 is installed. Is this intended, that from within sage the myhome/.matplotlibrc is used? I can of course use the GTKAgg. Thank you, again for the help. sTefan On Tuesday 15 December 2009 04:24:02 pm Marshall Hampton wrote: > Can you give an example of where this happens? > > -M.
