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

plt.axis('off')
plt.savefig(file_path, bbox_inches="tight", pad_inches = 0)

plt.savefig has those options in itself, just need to set axes off before
