Consider a following example that you want to have different alpha for edgecolor and face color (of course this does not work as of now), Circle((1, 1), 0.5, ec=(1, 1, 1, 0.2), fc=(1, 0, 0, 1), alpha=1) If alpha always overrides, it will override both alpha values of the edge color and facecolor, and we can't have different alphas for edge and face. And, in this case, I think the alphas should be multiplied. Similarly, Circle((1, 1), 0.5, ec=(1, 1, 1, 0.2), fc=(1, 0, 0, 1), alpha=0.5) I think it is natural to expect that the resulting alpha of ec to be 0.2*0.5. For the case of contourf, the problem in my point of view is not that the alpha is not overridden, but that contourf applies the same alpha twice. Whether set_alpha() method override or not would be an implementation detail, but I guess the above cases at least make some sense. -JJ ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
