Re: [matplotlib-devel] Exploring

[Damon M. <D.M...@wa...>]

Aha! Even without the text, i.e. setting label1On = False for all the major ticks, the behaviour I see is that with bbox_inches = 'tight' and pad_inches = 0.0 I get the saved figure which includes the black border line for the bottom and left edges, but not the top and right edges. This may have something to do with it. Maybe it's an issue with the bounding box not being 'inclusive' and leaving out the end points?

I've been searching in the figure.py source and nowhere can I see the bbox_inches='tight' keyword being tested for in the savefig() method. Having said that, all of the kwargs do get passed on to the canvas.print_figure() method, so I looked in the backend_pdf.py file but couldn't find a print_figure() method. Could someone point me in the right direction?
