在 matplotlib 中绘制 numpy arrays 的内容

Question

I am trying to plot the content of the arrays x and lj in the following code. However, the point in the plots are not the one inside the arrays. Can someone help me see the mistake I did? I am still new in python.

from matplotlib import pyplot as plt 
import numpy as np
import math 

lj=np.arange(10, dtype=np.float).reshape(10,1)
x=np.arange(10, dtype=np.float).reshape(10,1)

lj.fill(0)
x.fill(0)

for i in range(len(x)):
    x[i,0]=i*0.1
    lj[i,0]=4.0*( (1.0/(x[i,0]+0.0000001) )**12 - ( 1.0/(x[i,0]+0.0000001) )**6 )
    

for i in range(len(x)):
    print(x[i,0],"\t\t\t",lj[i,0])

plt.plot(x,lj,"o")
plt.show()

This is the content of the arrayys and the follwoiing one is the plot done with plt.plot()

0.0                      4e+84
0.1                      3999948000335.996

0.9                      6.636105087302215

Answer 1

Almost division by zero The plot is correct, lj[0] is almost equal to infinity, remove the first element, to get a better curve
