Changing the text of clabel in Matplotlib

Question

I would like to specify the text of my contour label (instead of the value of the contour I want to put a text) I've tried:

CS = contour(X, Y, Z, [0.5], linewidths=1, colors='k')
plt.clabel(CS, fontsize=10, inline=1, text=r'$\alpha=0$')

but it doesn't work. Any idea?

Answer 1

Try this:

plt.clabel(CS, fontsize=10, inline=1, fmt=r'$\alpha=0$')
