Suppose I want to make 2+ heatmaps (in the same or different figures), and the color matching ↔ will be the same among them.
By default, extreme values in the color palette (e.g., inkjet) will be used for the dynamic range of each heatmap separately (i.e. each imshow call), and I would like to make the display be the same, i.e. use global dynamic range.
I think the equivalent operator is that I would like to specify an absolute match somehow, whereas the imshow behavior given the cmap object refers to the dynamic range of input.
