Scatter

In this example we used a sequence of value for c, the accepted values for c argument are:

• A scalar or sequence of n numbers to be mapped to colors using cmap and norm.

• A 2D array in which the rows are RGB or RGBA.

• A sequence of colors of length n.

• A single color format string.

import matplotlib.pyplot as plt
import numpy as np

N = 100
x = 0.9 * np.random.rand(N)
y = 0.9 * np.random.rand(N)
s = (20 * np.random.rand(N)) ** 2
c = np.sqrt(s)

fig = plt.figure(figsize=(6, 5), tight_layout=True)
ax1 = fig.add_subplot(111)
ax1.grid()
ax1.set_xlabel("x")
ax1.set_ylabel("y")
ax1.set_title("Scatter plot")
sct = ax1.scatter(x, y, s=s, c=c, cmap="inferno", marker='^')
fig.savefig("scatter.png", dpi=200)
