Add an axes dynamically in matplotlib

using add_axes function

In this article, we will add an axis dynamically in matplotlib using add_axes function.

Steps

For adding an axis, we will follow these steps

   1. Create a figure object (which is a blank canvas)

   2. Call add_axes function to add axis.

   3. Plot the graph.

Example

import matplotlib.pyplot as plt
import array 

arr1 = array.array('i', [1, 2, 3])
arr2 = array.array('i', [4, 5, 6])

# Create a figure object
fig = plt.figure()
# add axis
axes = fig.add_axes([.1,.1,.8,.8])
# Plot graph
axes.plot(arr1,arr2)
# Show graph
plt.show()

In the above figure add_axes contain 4 parameters. First 2 parameters specify the distance of axis from left and bottom of the graph. Third and fourth parameter specifies the width and high of axis.
