How to do it...

The following code block plots four graphs, the fourth one is a subset of three axes, so it is axes within other axes (overlapping):

1. Fix random state for repeatability:

np.random.seed(19681211)

2. Define the figure with the figure size and image resolution and attach the figure to a canvas:

fig = Figure(figsize=(10,6), dpi=100)FigureCanvas(fig)fig.set(facecolor='c', alpha=0.1, edgecolor='m')

3. Define the first axes and set the title and ylabel:

ax1 = fig.add_axes([0.0, 0.55, 0.4, 0.4])ax1.set_ylabel('volts')ax1.set_title('a sine wave')

4. Define the data for the sine wave and plot it on the first axes:

t = np.arange(0.0, 1.0, 0.01)s = np.sin(2*np.pi*t)line, = ax1.plot(t, s, color='blue', lw=2)

5. Define the second axes and plot ...
