将乳胶写入轴

Question

plt.xlabel(r'$\rm log \: M_*$')

plt.ylabel(r’$\rm log \: M_{\bullet}$')

The x axis is able to be printed correctly. However, the y axis has an error. What's the cause for that error?

Answer 1

If I take the Arial's answer in order to give a general solution, you have a wrong typo in the y line.

You write :

plt.ylabel(r’$\rm log \: M_{\bullet}$')

But, after the r, you made ' instead of '

So, you just have to write :

plt.ylabel(r'$\rm log \: M_{\bullet}$')

And your problem is solved ;)
