Put legend outside the Matplotlib plot with Pandas in Python

In this tutorial, you will learn how to put Legend outside the plot using Python with Pandas.

A legend is an area of a chart describing all parts of a graph. It is used to help readers understand the data represented in the graph.

Libraries Used:

We will be using 2 libraries present in Python.

  • Pandas
    This is a popular library for data analysis.
  • Matplotlib
    Matplotlib is a multiplatform data visualization library that is used to produce 2D plots of arrays, such as a line, scatter, bar etc.

Syntax:

pd.DataFrame().T
This function is used to perform a transpose of the rows and columns by writing the rows as columns and columns as rows. is used to access the transpose() function.
plt.figure()
This function of the matplotlib library is used to create a figure.
plt.title(' ', color=' ')

This function is used to give the title for the plotted figure, and the argument color specifies the font color of the text.

d.plot(kind=' ',ax=f.gca())

This is used to specify the kind of chart we need such as line, bar.
‘line’ – line plot
‘bar’ – vertical bar plot
‘hist’ – histogram
‘pie’ – pie plot
‘scatter’ – scatter plot
ax is a matplotlib axes object and .gca() is used to get the current axes instance for the figure.

plt.legend(loc=' ',bbox_to_anchor=())

This function is used to specify the location and the exact coordinates to display the legend in the figure.
loc – specifies the location of the legend
bbox_to_anchor – states the exact coordinates of the legend.

plt.show()

This function is used to display the plotted figure.

Python program: Put legend outside the Matplotlib plot with Pandas

import pandas as pd
import matplotlib.pyplot as plt
data = {'1': {1: 20, 2: 21, 3: 22},
    '2': {1: 23, 2: 24, 3: 25}}

d = pd.DataFrame(data).T
f = plt.figure()
plt.title('Legend Outside', color='black')
d.plot(kind='bar', ax=f.gca())
plt.legend(loc='center left', bbox_to_anchor=(1.0, 0.5))
plt.show()

The output of the above program is given in the figure below:
