Can't turn-off ticks when sharing axis

Community matplotlib-users

Hello,

Consider my simple test case:

import matplotlib.pyplot as plt

fp = plt.figure()
ax1 = fp.add_subplot(4,1,1)
ax1.plot(range(10))
ax2 = fp.add_subplot(4,1,2)
ax2.plot(range(10))
ax1.xaxis.set_major_locator (plt.NullLocator ())

ax3 = fp.add_subplot(4,1,3)
ax3.plot(range(10))

Can’t turn off

ax3.xaxis.set_major_locator (plt.NullLocator ())
ax4 = fp.add_subplot(4,1,4, sharex=ax3)
ax4.plot(range(10))

Turn-off both ax3 and ax4

#ax3.xaxis.set_major_locator (plt.NullLocator ())

plt.show()

When I share x-axis in between two plots I can’t turn-off one axis’ major ticks. Depends on the location of the function call it either turn nothing or all. Is it intended or a mal-functioning? (Shared axis is for my screen view, I can live without it by turning off sharex option since it won’t make any difference for the final saved figures.)

Thanks.

The standard trick is to make the ticklabels on one axes invisible

for label in ax.get_xticklabels():
     label.set_visible(False)

Thanks John, This answer seems familiar to me :slight_smile: You have caught my intention correctly --not completely clearing the x-axis but rather turning-off the labels.

Your trick works independent from sharing state of an x-axis.

Alternatively, I use ax.xaxis.set_ticklabels (“”) to clear tick-labels when I don’t share the axis.
