That used pyCha is limited by design, we could add more complex charts via pycairochart (which is referenced by pyCha). Imho using Cairo directly would be to heavy. Nice looking with smoothness or interpolation is not my primary goal, though it could be for a customer. greets Tobias [1] http://bettercom.de/de/pycairochart -- [email protected] mailing list
