Where are the extra points on the graph?

Question

Python

I'm trying to display the points on the chart, but for some reason extra blue points are drawn, and the points from the array are shifted along X. What is the error?

import numpy as np
import matplotlib.pyplot as plt

dots = np.array()
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(dots, 'o')
ax.set_xlabel('x- points')
ax.set_ylabel('y-points')
ax.set_title('Simple XY point plot')
fig.show()

Answer 1

It is very difficult to understand what you are actually trying to do. But I suspect it is:

import numpy as np
import matplotlib.pyplot as plt
dots = np.array()
x=[i[0] for i in dots]
y=[i[1] for i in dots]
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(x,y, 'o')
ax.set_xlabel('x-points')
ax.set_ylabel('y-points')
ax.set_title('Simple XY point plot')
fig.show()
