 The optional parameter `ysize` can be used to change the size of the y-axis labels. The default value is 14 points.
 The optional parameter `bottom` can be used to control the bottom margin of the plot when using `plt.tight_layout(rect=[0, bottom, 1, 1])`. When `nothing`, the default tight layout is used.
