Next, we plot some data on each subplot using the `plot()` method of each `AxesSubplot` object. figure_object = plt.figure() Call the above Figure object's add_axes ( [left, bottom, width, height]) to create axes. 1. For example, lets say we have two subplots that share the x-axis: In this example, we create two subplots vertically stacked on top of each other using `subplots(2, 1)`. The `add_subplot()` method takes three arguments: the number of rows, the number of columns, and the index of the plot. Then we create a new figure with a size of `(8,6)` using `plt.figure()`, which returns an instance of `Figure`. Here we will use the contourf() function which draws the filled contours. The `plt.subplots()` function is used to create subplots. The `x` array is created using `np.linspace()` function which returns evenly spaced numbers over a specified interval. Each subplot can be customized independently by calling methods on its corresponding `ax` object. Example #1.
