Matplotlib: coloring axis/tick labels

问题:

How would one color y-axis label and tick labels in red?

So for example the "y-label" and values 0 through 40, to be colored in red.

import matplotlib.pyplot as plt import numpy as np  x = np.arange(10)  fig = plt.figure() ax = plt.subplot(111) ax.set_ylabel("y-label")  for i in xrange(5):     ax.plot(x, i * x, label='$y = %ix$' % i)  ax.legend()  plt.show() 

回答1:

  label = plt.ylabel("y-label")   label.set_color("red") 

similarly, you can obtain and modify the tick labels:

[i.set_color("red") for i in plt.gca().get_xticklabels()] 

回答2:

The xlabel can be colorized when setting it,

ax.set_xlabel("x-label", color="red") 

For setting the ticklabels' color, one may either use tick_params, which sets the ticklabels' as well as the ticks' color

ax.tick_params(axis='x', colors='red') 

Alternatively, plt.setp can be used to only set the ticklabels' color, without changing the ticks' color.

plt.setp(ax.get_xticklabels(), color="red") 

Note that for changing the properties on the y-axis, one can replace the x with a y in the above.
