python - Overlapping y-axis tick label and x-axis tick label in matplotlib

Question

If I create a plot with matplotlib using the following code:

import numpy as np
from matplotlib import pyplot as plt
xx = np.arange(0,5, .5)
yy = np.random.random( len(xx) )
plt.plot(xx,yy)
plt.imshow()

I get a result that looks like the attached image. The problem is the bottom-most y-tick label overlaps the left-most x-tick label. This looks unprofessional. I was wondering if there was an automatic way to delete the bottom-most y-tick label, so I don't have the overlap problem. The fewer lines of code, the better.

Answer 1

In the ticker module there is a class called MaxNLocator that can take a prune kwarg.
Using that you can remove the first tick:

import matplotlib.pyplot as plt
from matplotlib.ticker import MaxNLocator
import numpy as np
xx = np.arange(0,5, .5)
yy = np.random.random( len(xx) )
plt.plot(xx,yy)
plt.gca().xaxis.set_major_locator(MaxNLocator(prune='lower'))
plt.show()

Result:
