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' ) |
