How to hide axes in matplotlib.pyplot

Question

I put the image in a NumPy array, and draw it with the following code. How can I tell the program not to draw the axes, like (0, 100, 200...)

import matplotlib.pyplot as plt

plt.figure()
plt.imshow(output_ndarray)
plt.savefig(output_png)

Blatant plug: If you want to write a numpy array directly to a PNG file, you can use the package numpngw that I wrote. — Warren Weckesser

This is not hiding axes, but ticks and their labels.The Axes object also contains the image and other "artists". For those searching for actually hiding the axes: ax.set_visible(False) — mins

What is "aflw" (in the pictire embedded description)? AFLW, AFL Women's, Australia's national semi-professional Australian rules football league for female players? — Peter Mortensen

You can also use...

plt.axis('off')

This is the easiest way to to it. Note for object-oriented api, it is the same ax.axis('off') which is nice.
