[BUG] Colorbar label overlap

[Cyril-Meyer]

Label of the colorbar may overlap when small differences in values, e.g. :

Right now, I fixed adding the following code for my usage :

        if colorbar_orientation == "horizontal":
            from matplotlib.ticker import MaxNLocator
            locator = MaxNLocator(nbins=3)
            cbar.ax.xaxis.set_major_locator(locator)

I just override the default locator from Matplotlib, but this probably not the best solution.

After line 595 :

Multi_Comparison_Matrix/multi_comp_matrix/MCM.py

Lines 593 to 598 in 765fa80

	cbar = ax.figure.colorbar(
	im, ax=ax, shrink=shrink, orientation=colorbar_orientation
	)
	cbar.ax.tick_params(labelsize=font_size)
	cbar.set_label(label=capitalize_label(_colorbar_value), size=font_size)
