plt.subplot2grid(shape, location, rowspan, colspan)

In the following example, the graph object's3X3The grid fills the axes of different sizes in the span of rows and columns, each displaying a different graph.

Refer to the following example code:

　a3.set_title('log')
　plt.tight_layout()
　plt.show()
