How does parameters 'c' and 'cmap' behave in a Matplotlib scatter plot?

To get a sense of how the parameters c and cmap behave in a Matplotlib scatterplot, we can take the following steps −

• Set the figure size and adjust the padding between and around the subplots.
• Initialize a variable N to store the number of sample data.
• Create x and y data points using numpy.
• Plot x and y data points using scatter() method, color and colormap.
• To display the figure, use show() method.

Example

import numpy as np
from matplotlib import pyplot as plt

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

N = 50
x = np.random.randn(N)
y = np.random.randn(N)

plt.scatter(x, y, c=x, cmap="plasma")

plt.show()
