matplotlib.pyplot：设置轴单位的距离

Question

import numpy as np
import matplotlib.pyplot as plt

x = [0,5,9,10,15]
y = [0,1,2,3,4]
plt.plot(x,y)
plt.xticks(np.arange(min(x), max(x)+1, 1))
plt.show()

shows

But if I set unit to 0.5: plt.xticks(np.arange(min(x), max(x)+1, 0.5)) shows

x-axis is hardly readable.

Is there a way to set distance for every x-axis unit so it could extend the plot automatically (on x direction)?

Answer 1

This works:

import numpy as np
import matplotlib.pyplot as plt

x = [0,5,9,10,15]
y = [0,1,2,3,4]
plt.figure(figsize=(20,10))
plt.plot(x,y)
plt.xticks(np.arange(min(x), max(x)+1, 0.5))
plt.show()

Operating on size of the figure does the job. Play with it, find your desired size/ratio etc.
