Cleanest way to hide every nth tick label in matplotlib colorbar?

Question

The labels on my horizontal colorbar are too close together and I don't want to reduce text size further:

cbar = plt.colorbar(shrink=0.8, orientation='horizontal', extend='both', pad=0.02) cbar.ax.tick_params(labelsize=8) 

I'd like to preserve all ticks, but remove every other label.

Most examples I've found pass a user-specified list of strings to cbar.set_ticklabels(). I'm looking for a general solution.

I played around with variations of

cbar.set_ticklabels(cbar.get_ticklabels()[::2]) 

and

cbar.ax.xaxis.set_major_locator(matplotlib.ticker.MaxNLocator(nbins=4)) 

but I haven't found the magic combination.

I know there must be a clean way to do this using a locator object.

Answer 1

For loop the ticklabels, and call set_visible():

for label in cbar.ax.xaxis.get_ticklabels()[::2]:     label.set_visible(False)
