tick sizes

Community matplotlib-users

Hi All,

I am trying to modify tick sizes and labels. Reading documents and examples, I have found an easy way to modify the labels,

import matplotlib.pyplot as plt

ax = plt.axes()
font_size = 24

plt.setp(ax.get_xticklabels(),fontsize=font_size)

but I am struggling to find such a nice solution for the tick size. I would like to change the size of the major and minor ticks independently. But the best I have come up with so far is a brute force double loop (I tried calling "major=False" but "major" is not a recognized kwarg)

for tick in ax.xaxis.get_ticklines(minor=True):
    tick.set_markersize(5)
for tick in ax.xaxis.get_ticklines(minor=False):
    tick.set_markersize(10)

I assume there is some nice solution like for the tick labels, but I have not found it.

Anyone figured this one out yet?

Thanks,

Andre

Hi Andre,

You should be able to set the size with the following:

params = {‘length’: 10}
axis = plt.axes().xaxis
axis.set_tick_params(which=‘major’, **params)

You can also use ‘minor’ instead of ‘major’ to set the minor ticks. There are a number of different valid values for the params dict, including direction, width, and color.

Hi Ben,

Would you expect this to work on Matplotlib 0.99.3?

I get the following error

AttributeError: ‘XAxis’ object has no attribute ‘set_tick_params’

Thanks,

Andre

Hmm, no, it looks like the tick_params were added in 1.0. I can also get it to work using

plt.setp(ax.xaxis.get_ticklines(minor=False), markersize=10)

but I’m using matplotlib 1.0.1. I’m not sure if neither of those solutions work.

well I knew there was a better solution, thanks.

I guess I’ll just have to upgrade my installation.
