Hej guys, I encountered a strange behaviour with 0.87.5. One central line of the = horizontal grid is not drawn correctly. It starts a pixel higher on the = left than it ends on the right and is thicker for a large part in the = middle. See this: http://img339.imageshack.us/img339/6782/graphwk7.png Is this a known bug? Chris P.S. I can't update matplot in my work environment, otherwise I would = have tried 0.90.1
