Re: [igraph] how to plot graph on matplotlib figure?

[Diederik van Liere]

Hi Tamas,

Just one final question about plotting a graph using matplotlib. It seems that the visual_style dictionary is not passed along to the renderer. Is this a limitation of using matplotlib or should the code snippet be extended with support for a visual_style dictionary?

Thanks so much!

best,

Diederik

Hi Diederik,

Hmmm, 'ctx' is an undocumented attribute of RendererCairo that should
hold the Cairo context on which matplotlib is drawing. It worked for me
with my version of Matplotlib (0.98.5.2), it looks like they have
changed something between Matplotlib 0.98.5.2 and 0.99.3. I'll try to
get hold of the most recent version and see what the new name of this
attribute is. Maybe try replacing 'renderer.ctx' with 'renderer.gc.ctx'
first, this seems to work in 0.99.1
