Why is the add_subplot() function of Matplotlib not functioning as expected when used in a for loop?

edit

The add_subplot() function of Matplotlib is not functioning as expected when used in a for loop because it creates a new subplot each time it is called. If the loop iterates more than once, it will create multiple subplots on top of each other, which may result in unexpected output. To avoid this, you can either call the subplots() function before the loop to create a grid of subplots, or you can use plt.figure() to create a new figure for each iteration of the loop.
