I just made some experiments with Matplotlib and what i noticed is that all that is generated using matplotlib appear in a new window that doesn't seem to be tightly linked to qgis. The only "link" i see is a save button enabling plot export as raster images.
My aim would be to stack(/merge) graphics/plots or (georeferenced) shapes generated with matplotlib with layers in a qgis composer.
Is there a way to do that ? (i mean a tighter/quicker way than adding image objects in the composer).
Would it be a way to share a common "coordinate system" between map objects and rasters generated by Matplotlib ?
If possible could someone point me in the right direction ?
