How to remove frame from matplotlib (pyplot.figure vs matplotlib.figure ) (frameon=False Problematic in matplotlib)

Question

To remove frame in figure, I write

frameon=False

works perfect with pyplot.figure, but with matplotlib.Figure it

Answer 1

The easiest way to get rid of the the ugly frame in newer versions of matplotlib:

import matplotlib.pyplot as plt
plt.box(False)

If you really must always use the object oriented approach, then do: ax.set_frame_on(False).
