Matplotlib 3.0 Cookbook

How to do it...

The following code block plots the required charts and saves them into a PDF document as three separate pages. All these plots have been used in earlier chapters, so the details of plotting each of them are already familiar to you. Here, the focus is how these charts are arranged to save in various pages of the PDF document:

1. Set the seed for repeatability:

np.random.seed(19681211)

2. Define a function to draw a polar plot:

def Plot_Polar():    plt.figure(figsize=(6, 4))    N = 250    r = 10 * np.random.rand(N)    theta = 2 * np.pi * np.random.rand(N)    area = r**2     colors = theta    ax1 = plt.subplot(121, projection='polar')    ax1.scatter(theta, r, c=colors, s=area, cmap='plasma',                 alpha=0.6) ax1.set_title('Polar Plot', color='m', size=15, ...
