Scatter plots show how much one variable is affected by another. The relationship between two variables is called their correlation.
import matplotlib.<< your code goes here >> as plt
rand to generate random values for the x-, and y-coordinates
from numpy.random import << your code goes here >>
Now we will call the
scatter module to generate the scatter plot.
for color in ['red', 'green', 'blue']: n = 100 x, y = rand(2, n) scale = 500.0 * rand(n) ** 5 plt.<< your code goes here >>(x, y, s=scale, c=color, alpha=0.3, edgecolors='blue') plt.grid(True) plt.show()
s is a scalar or array-like shape, and is an option argument.
c defines the color.
alpha defines the alpha blending value, or the transparency.
edgecolor is the line color of the shapes.
grid displays the plot grid.
