How to do it...

The following code block plots two graphs to demonstrate axes and blended co-ordinate systems:

1. Fix the random state for repeatability and set the style to be used in this session:

np.random.seed(19681211)plt.style.use('ggplot')

2. Define the figure with size and add an axis to it:

fig = plt.figure(figsize=(10,5))ax1 = fig.add_subplot(121)

3. Define the data for a scatter plot and plot it using the plot method, instead of the scatter method:

x, y = 50*np.random.rand(2, 500)ax1.plot(x, y, 'cH') 

4. Define an ellipse patch and add it to the axes:

ellipse = patches.Ellipse((0.5, 0.5), 0.6, 0.3, transform=ax1.transAxes,                           facecolor='blue', alpha=0.3)ax1.add_patch(ellipse)# remove the comment below to check if Ellipse remains at the ...
