How to plot a given number of points on a function plot in PyPlot?

Question

Python

The number of points when plotting the graph of the function was set somehow like this:
t = linspace(0, 0.8, 251)
Is it possible to set in some alternative way the number of points to the function when I build, for example, the dependence of one array on another:
plt.plot(array1, array2, '-g', label='label1')? With pyplot?

Answer 1

What does it mean to set the number of points?
pyplot doesn't know what function you're looking at, so it won't be able to plot you for certain points.
To display only those points that you need, you need to use slices.
For example:

import matplotlib.pyplot as plt
import numpy as np


t = np.linspace(0, np.pi, 314)
y = np.sin(t)

plt.figure(1)
plt.plot(t, y, '-g')
plt.plot(t[100:150:5], y[100:150:5], 'og')
plt.plot(t[::10], y[::10], '*r')
plt.show()
