[Qgis-developer] Expression based diagrams ?

[Matthias Kuhn]

Hi Michael,

There is also a feature request open for this
http://hub.qgis.org/issues/6768

I think this won't be an option for 2.0 but if there is a sponsor 
around, I could make it for 2.1. But we should first think about what 
features this would include.
Do you see a benefit of having data defined colors? Having the same 
class with different colors on different diagrams seems odd to me. Can 
you give an example of where this might be useful?
