Hi,
I have been unable to get the pdf backend to respect the settings for solid_joinstyle properly. When doing a plot using the default matplotlibrc I get rounded joins when saving as png but mitered when using pdf. I have also tried to set the joinstyle="round" directly in the plot command with the same result, pdf ignores the setting but png respects it.
I'm using a current build from svn on windows with python 2.5
