As far as I know, OSGeo4W as well as the standalone installer contains matplotlib 0.99, while Contour plugin 0.9 require matplotlib 1.0.1
So you can either: - install matplotlib 1.0.1 by your own - contact OSGeo4W matplotlib maintainer: http://trac.osgeo.org/osgeo4w/wiki/pkg-python-matplotlib - contact the plugin author: http://www.blogger.com/profile/11552330570446337100 - use contor from GdalTools _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
