从 matplotlib 更改 barh plot 中 y 轴上的字体大小

Question

I want to change the fontsize of the lable on the y axis of a horizontal barplot (ie make the fontsize of "Question 1", "Question 2" bigger). I could not find the solution from the documentation of barh . Is it possible to do it. And if yes, where can the answer be found?

import matplotlib.pyplot as plt
import numpy as np
 
x = np.array(["Question 1", "Question 2", "Question 3", "Question 4"])
y = np.array([3, 8, 1, 10])
 
plt.barh(x, y)
plt.tight_layout()
plt.show()

Answer 1

Use plt.yticks :

import matplotlib.pyplot as plt
import numpy as np
 
x = np.array(["Question 1", "Question 2", "Question 3", "Question 4"])
y = np.array([3, 8, 1, 10])
 
plt.barh(x, y)
plt.yticks(fontsize=20)
plt.tight_layout()
plt.show()
