stackoverflow.com › questions › 3373256python - Set Colorbar Range in matplotlib - Stack Overflow With the two different limits you can control the range and legend of the colorbar. In this example only the range between -0.5 to 1.5 is show in the bar, while the colormap covers -2 to 2 (so this could be your data range, which you record before the scaling). So instead of scaling the colormap you scale your data and fit the colorbar to that.
