How to display only some points on the x-axis in matplotlib python?

Question

Python

I have this code:

r = [5, 6.5, 8, 7, 9, 8, 11, 15, 18, 22]
x = ["01:15:03", "01:15:13", "01:15:25", "01:16:13", "01:17:13", "01:17:58", "01:18:13", "01:19:13", "01:20:13", "01:21:13"]
plt.title('График температуры')
plt.xlabel("Время")
plt.ylabel("Температура '°C'")
plt.grid(True)
plot(x, r, '-r', mec='b')
savefig('example.png')

I get such a picture


Tell me how to get rid of the overlay of inscriptions along the X axis?
Can I make it so that a certain number of points are plotted along the axis?

Answer 1

My God, 257 times already wrote the answer personally, including at this forum. Well, is it really difficult to find the answer on your own?
Explore the matplotlib.ticker module further on the MultipleLocator methods from it and the set_major_locator from matplotlib.pyplot.
Well, or you can just rotate the labels so that they don't overlap - the xticks() method parameter rotation=90.
