[Matplotlib-users] range in the colorbar
Hi, I am generating a scatter plot with a colorbar, and want to pass on the colorbar to some function to do something with it, like plt.scatter(px, py, c=pz, ...) cb = plt.colorbar() foo(cb) My question: How can I extract the range of the colorbar from the cb object? The colorbar extends from min(pz) to max(pz), but can I access these values from the cb object alone, without the need to pass pz to foo as well?
