This recent NeuroStars post suggests that we are not properly supporting colorbars with the newest matplotlib release (3.5.1). Please see the post for an example rendering.

Nilearn version: 0.9.0

Expected behavior

The colorbar size would be appropriately linked to the figsize.

Actual behavior

The colorbar size does not scale with the figure.

Steps and code to reproduce bug

plotting.plot_stat_map(img, cut_coords=[20, -50, -8], colorbar = True, draw_cross = False, cmap = ‘cyan_copper’, vmax = 7)
