Plotting a scatter of points

A simple example showing how to plot a scatter of points with matplotlib.

import numpy as np
import matplotlib.pyplot as plt

n = 1024
rng = np.random.default_rng()
X = rng.normal(0, 1, n)
Y = rng.normal(0, 1, n)
T = np.arctan2(Y, X)

plt.axes((0.025, 0.025, 0.95, 0.95))
plt.scatter(X, Y, s=75, c=T, alpha=0.5)

plt.xlim(-1.5, 1.5)
plt.xticks([])
plt.ylim(-1.5, 1.5)
plt.yticks([])

plt.show()
