Scatter plot

Another basic plot type is scatter plot, a plot of dots. You can draw it by calling plt.scatter(x,y). The following example shows a scatter plot of random dots:

import numpy as npimport matplotlib.pyplot as plt# Set the random seed for NumPy function to keep the results reproduciblenp.random.seed(42)# Generate a 2 by 100 NumPy Array of random decimals between 0 and 1r = np.random.rand(2,100)# Plot the x and y coordinates of the random dots on a scatter plotplt.scatter(r[0],r[1])# Show the plotplt.show()

The following plot is the result of the preceding code:
