 [Matplotlib-users] preventing extra whitespace around figure From: Michael Hearne - 2008-02-29 02:39:13 Attachments: Message as HTML ```Does anyone know of a way of preventing the generation of extra whitespace around the edge of a figure?

I've done some experiments where I reduce the bounding box by hand, which works really well - the only problem is I need a way to determine where the edge of my plot really is. In Basemap, there is a box drawn around my map. I'm pretty sure this is just the axis border, and I need to find a way to determine which of the many drawing commands in the postscript file represents this border. Is there a way to set the color of this plot box in matplotlib, so that I can use that as a clue in the postscript?
