How do I extend the margin at the bottom of a figure in Matplotlib?

Question

The following screenshot shows my x-axis.

I added some labels and rot

Answer 1

Subplot-adjust did not work for me, since the whole figure would just resize with the labels still out of bounds.

A workaround I found was to keep the y-axis always a certain margin over the highest or minimum y-values:

x1,x2,y1,y2 = plt.axis()
plt.axis((x1,x2,y1 - 100 ,y2 + 100))
