Re: [Matplotlib-users] Problem generating postscript

Hi thanks a lot for the quick tip. But no xpdf does not do it (I had tried it). Just to be consistent below is an account of my config (may not help much). I'll tried to write some simple script to reproduce the bug and post it but I am afraid this won't be very simple on my side. cheers Eric
