this report has been filed here: https://bugs.edge.launchpad.net/ubuntu/+source/poppler/+bug/345803 "Evince shows a rendering glitch while rendering graphs generated by matplotlib - it draws an extraneous horizontal line across the middle of the graphs. The glitch isn't present in Adobe Reader. I've attached a PDF with the glitch, scroll down to the bottom to view the graphs."
