python matplotlib在一张画布上画多个图的两种方法,plt.subplot(),plt.subplots()。
`plt.subplot(2, 1, 1)` is a function call from the matplotlib library in Python.
It is used to create subplots within a single figure. The function takes three arguments:
1. `2` - number of rows of subplots
2. `1` - number of columns of subplots
3. `1` - index of the subplot being created
In this case, `plt.subplot(2, 1, 1)` creates the first subplot in a 2-row, 1-column grid of subplots. The `1` at the end indicates that this is the first (top) subplot.
The second subplot would be created using `plt.subplot(2, 1, 2)`, which creates the second (bottom) subplot.
