How to change the size of the numbers under the axis

Hello,

Do you know to change the size of the numbers under the axis?

fabien

import matplotlib
matplotlib.rcParams['axes.labelsize'] = 12.0

Hope this helps.

You want to modify “xtick.labelsize” or “ytick.labelsize”. By default, they are “medium”, but you can use a number for it as well. “axes.labelsize” effects the axes labels, not the labels for the ticks.

Hi,

But how can I do it for every graph and without creating axis?

I’ve seen this example:

import numpy as np
import matplotlib.pyplot as plt

# plt.figure creates a matplotlib.figure.Figure instance
fig = plt.figure()
rect = fig.patch # a rectangle instance
rect.set_facecolor('lightgoldenrodyellow')

ax1 = fig.add_axes([0.1, 0.3, 0.4, 0.4])
rect = ax1.patch
rect.set_facecolor('lightslategray')

for label in ax1.xaxis.get_ticklabels():
    # label is a Text instance
    label.set_color('red')
    label.set_rotation(45)
    label.set_fontsize(16)

I don’t manage to use only label.set_fontsize(16). It looks so complicated.

We just told you:

import matplotlib

matplotlib.rcParams[‘xticks.labelsize’] = 12.0

Whenever a plot is made, it obtains the defaults from the rcParams. Note, if you are changing the rcParams after creating a plot, then this would have no effect.

Cheers!

I’ve tried also but it returns an error:

matplotlib.rcParams[‘xticks.labelsize’] = 12.0
File “C:\Python27\lib\site-packages\matplotlib_init_.py”, line 653, in setitem
See rcParams.keys() for a list of valid parameters.’ % (key,))
KeyError: ‘xticks.labelsize is not a valid rc parameter.See rcParams.keys() for a list of valid parameters.’

It's actually 'xtick.labelsize'. No 's'.

Thanks,

I’ve found the problem. I use xlabel(“name of my axis”, size= 30) after
matplotlib.rcParams['xtick.

labelsize’] = 12.0 and it cancel it! Is it possible to have a name on the axe and matplotlib.rcParams[‘xticks.
labelsize’] = 12.0 ??

I’m just trying to plot a graph and add a label to each axis of that graph and change the labelsize of the ticks.

Could you post your code? What you are describing shouldn’t happen. Also, which version of matplotlib are you using?

I just create two vectors from a .txt file and I plot them.
I think I have the latest version of matplotlib. I have at least the
last version of python(x,y)

from pylab import*

In your matplotlib config file
axes.titlesize : 10 # fontsize of the axes title
axes.labelsize : 10 # fontsize of the x any y labels
(see http://matplotlib.sourceforge.net/users/customizing.html )

Hi,

I think I was tired yesterday.
matplotlib.rcParams['xtick.labelsize'] = 20.0 works perfectly also
with xlabel("name", size= 30)

Thanks all,
