# color bar yticklabels manipulation
cbar.ax.set_yticklabels(['{:.0f}'.format(x) for x in np.arange(cbar_min, cbar_max+cbar_step, cbar_step)], fontsize=16, weight='bold')
# For every axis, set the x and y major locator
for axi in ax.flat:
axi.xaxis.set_major_locator(plt.MaxNLocator(3))
axi.yaxis.set_major_locator(plt.MaxNLocator(3))
# get float of 2 decimals for the xticks
['{:,.2f}'.format(x) for x in xticks]
