Matplotlib: set axis tight only to x or y axis

Question

I have a plot look like this:

Obviously, the left and right side is a waste of space, so I set

plt.axis(\'tight\')

Answer 1

You want to use matplotlib's autoscale method from the matplotlib.axes.Axes class.

Using the functional API, you apply a tight x axis using

plt.autoscale(enable=True, axis='x', tight=True)

or if you are using the object oriented API you would use

ax = plt.gca()  # only to illustrate what `ax` is
ax.autoscale(enable=True, axis='x', tight=True)

For completeness, the axis kwarg can take 'x', 'y', or 'both', where the default is 'both'.
