Is there a way to change the transition values of a continuous colormap (cmap) in matplotlib? I want to use "vlag" to color a heatmap, however my values only typically range from 0 to 0.6 (instead of 0-1). I could renormalize my data or use vmin & vmax, however I was curious if there was a way to set transition points for vlag between 0-1. There are three colors in vlag (blue, white, and red). Having set transition points will allow for an apples to apples comparison between different heatmaps.
