figure object and subplots function in matplotlib

In this article, we will discuss figure object and subplots function in matplotlib.

Figure object

   1. Figure is outmost container of matplotlib graphics.

   2. Figure contains multiple axes.

   3. Figure object is useful if you want to perform figure-level changes.

Here is the small piece of code for figure

import matplotlib.pyplot as plt

fig = plt.figure()

In the above code, ‘fig’ is the figure object. We will investigate it in greater details in subsequent articles.

Subplots function

Subplots function returns a tuple containing figure and axes objects. Consider the following example

import matplotlib.pyplot as plt

fig = plt.figure()

X = plt.subplots(nrows = 2, ncols= 2)  # a figure with a 2x2 grid of Axes

x = 0
while x < len(X):
    print(X[x])
    x = x + 1

plt.show()

When you run the above program, you can see that subplots function returns 1 figure and 4 axes.
