[Qgis-developer] custom charts?

[Neumann, Andreas]

Pretty cool - so we can deliver script-generated SVG code instead of a
filename? Nice! 

Care to do a blog post with some example? This sounds quite exciting to
me.

Are you sure? This would mean that the value(!) of an attribute would
contain the actual svg (code, not filename).
Any example on how to use that with styling then? 
Hmmm exact, I don't think you can include the content (I tried to
include a data url but it does not work).

Same here, while we managed to get for example colors dynamic, we could
not find a way (yet) to set the marker-svg once filename is retrieved
from an attribute...

Happy to get an example or pointers :-) 
with an SVG-marker the filename can be "data-defined", so you can for
instance use an expression like '/xxx/mymarker_' || id || '.svg'
