Re: [Matplotlib-users] subplot axis ticks

Yes, this works fine:

import numpy as np
import matplotlib.pyplot as plt

eels= np.random.rand(12)
averspe = np.random.rand(12)
fig,azal = plt.subplots(1,1)
azal.locator_params(nbins=10)
azal.plot(eels, averspe, label='data')

Cheers,  Jody

PS, easiest is to include self-contained examples.  i.e. we don’t have “averspe” and “eels” so its hard for us to see what you are seeing.
