subplot axis ticks

Hi all,

I’m trying to set the NUMBER of ticks on a subplot axis.

Googling I’m finding only how to set the ticks values…but what if I don’t know them and for visual reasons I would like to have a fixed number of ticks?

thanks

Gabriele

http://stackoverflow.com/questions/6682784/how-to-reduce-number-of-ticks-with-matplotlib

is the easy way. You can also write your own “Locators” that are more sophisticated if you have some ideas in mind (i.e. close to 5 ticks, but you’d prefer whole numbers, etc).

Hi,

I already saw that stack overflow page but

this is my code:

azal = rif.add_subplot(111)

azal.plot(eels*(10**9), averspe, label=‘data’)

azal.plot(eels*(10**9), beck, label=‘fit’)

I tried to add both

azal.yaxis.locator_params(nbins=4)

or

azal.locator_params(nbins=4)

and it doesn’t work.

I wonder if setting the locator params prior to plotting would fix that?

Might be one of those rare situations where the order of commands matter in matplotlib.

You need to do the azal.locator_params() call after you create azal. You would get errors otherwise.

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.
