Math text in matplotlib is rendered smaller than the regular text as show by
ax.set_xlabel(r'Variable $\alpha$')
Further details on this problem are found in Matplotlib: Change math font size.
The accepted solution was setting math font to regular font. But then variable in math mode are not italic as they should be.
I need variables in math mode and of the same size as text.
How can this be achieved and why is this not the default?
