Why set_xticks doesn't set the labels of ticks?

Question

import matplotlib.pyplot as plt  x = range(1, 7) y = (220, 300, 300, 290, 320, 315)  def test(axes):     axes.bar(x, y)     axes.set_xticks(x, [i+100 for i in x])  fig, (ax1, ax2) = plt.subplots(1, 2) test(ax1) test(ax2) 

I am expecting the xlabs as 101, 102 ... However, if i switch to use plt.xticks(x, [i+100 for i in x]) and rewrite the function explicitly, it works.

Answer 1

.set_xticks() on the axes will set the locations and set_xticklabels() will set the displayed text.

def test(axes):     axes.bar(x,y)     axes.set_xticks(x)     axes.set_xticklabels([i+100 for i in x]) 

Answer 2

Another function that might be useful, if you don't want labels for every (or even any) tick is axes.tick_params.

def test(axes):     axes.tick_params(axis='x',which='minor',direction='out',bottom=True,length=5)
