如何在我的图中 matplotlib python 2.7 或 3.5 中的 X 轴上设置不同的“步长”？

Question

I have some code:

import numpy as np
import matplotlib.pyplot as plt

x = [0,1,2,3,4,5,6]
y = [5,6,7,10,100,10000,1000000]
plt.plot(x,y)
plt.xticks(np.arange(min(x), max(x)+1, 1.0))
plt.show()

You see, the biggest value is 1000000, if one value is very big, the other small values seems zero from the chart.

Can i use different steps for the axis Y?

The axis Y like this: small step... middle step... big step...

Answer 1

You could use a logarithmic scale by setting plt.yscale() :

import numpy as np
import matplotlib.pyplot as plt

    plt.yscale('log')
    x = [0,1,2,3,4,5,6]
    y = [5,6,7,10,100,10000,1000000]
    plt.plot(x,y)
    plt.xticks(np.arange(min(x), max(x)+1, 1.0))
    plt.show()
