Make longer subplot tick marks in matplotlib?
I am trying to alter the tick marks along the axes of a python multipanel subplot. I have two panels that share a common x-axis. I have made the border around the plot thicker as well as making all of the tick marks along the axes thicker. I have two questions:
How can I make all tick marks (both axes) longer so they are more visible?
How do I add smaller but still noticable tick marks between major tick marks?
Here is a minimum working example of what I have so far.
from numpy import *
from scipy import *
from pylab import *
from random import *
import pylab
import matplotlib.pyplot as plt
#make the axis border thick
pylab.rc("axes", linewidth=4.0)
pylab.rc("lines", markeredgewidth=4)
#create a figure with two panels that shares the x-axis
f, (ax1, ax2) = plt.subplots(2, sharex=True, sharey=False)
#example figure1
ax1.plot(range(2),range(2),linewidth=2)
#example figure 2
ax2.plot(range(2),range(2),linewidth=2)
# Fine-tune figure; make subplots close to each other and hide x ticks for
# all but bottom plot.
f.subplots_adjust(hspace=0)
plt.setp([a.get_xticklabels() for a in f.axes[:-1]], visible=False)
show()
Answer
Try the following:
#example figure1
ax1.plot(range(2),range(2),linewidth=2)
ax1.minorticks_on()
ax1.tick_params('both', length=20, width=2, which='major')
ax1.tick_params('both', length=10, width=1, which='minor')
You can repeat the same for ax2. Does this work for you?
