Here is the explanation of the code:
- plt.close('all') clears the space before starting a new figure.
- fig = plt.figure(1, figsize=(12, 9)) defines figure 1 with a size equal to (12, 9).
- ax1 = plt.subplot2grid((3, 3), (0, 0)) creates ax1 axes, where the first plot will be drawn, and ax1 is the first axes in a 3 x 3 grid of 9 axes. Python indexing starts from 0, 1, and 2, which represent the first, second, and third row or column.
- ax2 = plt.subplot2grid((3, 3), (0, 1), colspan=2) creates ax2 axes, which spans two columns of the 3 x 3 grid, starting at the first row and the second column.
- ax3 = plt.subplot2grid((3, 3), (1, 0), colspan=2, rowspan=2) creates anax3 axes, which spans two columns and two rows, starting at the second ...
