Bug summary

The default for the indices keyword in the find_nearest_contour function within countour.py is defined incorrectly in the code. Line 1377 should be "indices = range(len(self.layers))" instead of "indices = range(len(self.levels))."

Code for reproduction

importnumpyasnpimportmatplotlib.pyplotaspltxy=np.indices((100,100))img=np.exp(-np.pi*(np.sum((xy-50)**2,0)/20.**2))cs=plt.contourf(img,50)cs.find_nearest_contour(20,20,pixel=False)

Actual outcome

Traceback (most recent call last):
File "", line 1, in
File "/opt/local/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/matplotlib/contour.py", line 1388, in find_nearest_contour

Expected outcome
