How to change the legend’s font size in Matplotlib?

The legend is actually a Colorbar object. To change the legend’s font size, we have to get hold of the Colorbar’s Axes object, and call .tick_params () on that. First, we call the .plot () method as usual, but we capture the return value which is the Axes of the map. We can use this to get hold of the Figure that contains the Axes.

How to change the size of the colorbar axes of an image?

The default value of the shrink attribute is 1. With this class, you can change the size of the colorbar axes however height will be the same as the current axes. Here we are using axes_divider.make_axes_locatable function which returns the AxisDivider object for our current axes in which our image is shown.
