Hi together!:) I've got a problem concerning the ticks on a colorbar for a contourf plot. Let's say I've got 20 Levels in the contourf plot. (plt.contourf(x,y,z, levels) ) Somehow, I do only get 17 'segments' in the corresponding colorbar. But this ...
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.

Apr 21, 2020 · Contour plots also called level plots are a tool for doing multivariate analysis and visualizing 3-D plots in 2-D space. If we consider X and Y as our variables we want to plot then the response Z will be plotted as slices on the X-Y plane due to which contours are sometimes referred as Z-slices or iso-response.
