How to rotate x labels using Pygal? (original) (raw)

Last Updated : 23 Jul, 2025

Prerequisites: Pygal

Pygal is a graphics and user interface library for Python that provides functionality commonly required in designing and science applications. While making a plot it is important for us to optimize its label, title, size. In this article, we will see how we can rotate the X-Label value of the plot window in the Pygal module. This can be done by passing the angle of rotation to x_label_rotation parameter.

Here are various ways to change the default plot x_label as per our requirement.

Approach:

• Import required module.
• Create a chart object.
• Pass x_label_rotation value in function.
• Label the graph.
• Display Graph.

Implementation of the concept discussed above is given below:

Example 1:

Python3 `

import library

import pygal import numpy

creating the chart object

chart = pygal.Bar(x_label_rotation=20)

Random data

chart.x_labels = [ 'First Bar !', 'Second Bar !', 'Third Bar !', 'Fourth Bar !'] chart.add('line', [0.1, .034, .065, .035])

naming the title

chart.title = 'Bar Chart'

chart.render_to_png('img.png');

`

Output:

Example 2:

Python3 `

importing pygal

import pygal import numpy

creating the chart object

chart = pygal.Line(x_label_rotation=90)

Random data

chart.x_labels = [ 'First Point !', 'Second point !', 'Third Point !', 'Fourth Point !'] chart.add('line', [0.1, .034, .065, .035])

naming the title

chart.title = 'Line Chart'

chart.render_to_png('img.png')

`

Output:
