Prerequisites: pygal
Pygal is a graphics and user interface library for Python that provides functionality commonly required in designing and science applications.
In this article, we will see how we can change chart color in the Pygal module. While making a chart it is important for us to adjust color The following methods are used for the creation of the graph and corresponding color change of the graph. Here we will see some examples to illustrate our point as per our requirement.
Approach:
- Import required module.
- Create a chart object.
- Change the color of the chart.
- Label the graph.
- Display Graph.
Implementation of the concept discussed above is given below:
Example 1:
Python3
import pygal from pygal.style import Style # change graph color custom_style = Style( colors=('#E80080', '#404040', '#9BC850', '#ffeb44', '#ff00ff')) # creating Pie chart object pie_chart = pygal.Pie(inner_radius=1, style=custom_style) pie_chart.title = 'Number of people using social media (in million)'pie_chart.add('Signal', 14.36) pie_chart.add('Instagram', 26.01) pie_chart.add('Twitter', 8.8) pie_chart.add('Facebook', 30.32) pie_chart.add('Youtube', 20.3) pie_chart.render_to_png('aa.png') |
Output
Example 2:
Python3
# importing pygal import pygal from pygal.style import Style # change graph color custom_style = Style( colors=('#ffebcd', '#daa520', '#9BC850', '#ffeb44', '#ff00ff')) # creating Bar chart object pie_chart = pygal.Bar(style=custom_style) # chart data pie_chart.add('Hindu', 13.36) pie_chart.add('Muslim', 21.01) pie_chart.add('Buddhist', 5.8) pie_chart.add('Christian', 33.32) pie_chart.add('Others', 26.3) # naming the title pie_chart.title = 'World religion population in 2007 (in %)' pie_chart.render_to_png('aa.png') |
Output
Example 3:
Python3
# importing pygal import pygal from pygal.style import Style # change graph color custom_style = Style( colors=('#ffebcd', '#daa520', '#9BC850', '#ffeb44', '#ff00ff')) # creating Dot chart object pie_chart = pygal.Dot(style=custom_style) # chart data pie_chart.add('Hindu', 13.36) pie_chart.add('Muslim', 21.01) pie_chart.add('Buddhist', 5.8) pie_chart.add('Christian', 33.32) pie_chart.add('Others', 26.3) # naming the title pie_chart.title = 'World religion population in 2007 (in %)' pie_chart.render_to_png('aa.png') |
Output
