Pyramid chart in pygal
  • Last Updated : 03 Jul, 2020

Pygal is a Python module that is mainly used to build SVG (Scalar Vector Graphics) graphs and charts. SVG is a vector-based graphics in the XML format that can be edited in any editor. Pygal can create graphs with minimal lines of code that can be easy to understand and write.

Pyramid Chart

The pyramid graph is a chart whose shape is a triangle or pyramid. These charts are beneficial in use when the data is organized in some kind of apparatus way. The increase or decrease of the pyramid indicates some kind of progressive order like more important to least important. It can be created using the Pyramid method.

Syntax:

pyramid_chart = pygal.Pyramid()

Example 1:




import pygal
import random
  
# Random Data
data = [numpy.random.rand(100), numpy.random.rand(100),
        numpy.random.rand(100), numpy.random.rand(100)]
  
types = ['A', 'B',
         'C', 'D', ]
  
pyramid_chart = pygal.Pyramid()
  
# Naming the title
pyramid_chart.title = 'Pyramid Chart'
  
for type, dat in zip(types, data):
    pyramid_chart.add(type, dat)
  
pyramid_chart

Output:



Example 2:




import pygal
import random
  
  
# Random Data
data = [[26, 22, 39, 39, 32, 30, 33, 24, 24, 30], 
        [31, 40, 22, 30, 21, 34, 40, 32, 25, 31], 
        [37, 27, 31, 20, 38, 32, 24, 39, 29, 22], 
        [38, 30, 20, 29, 33, 23, 32, 33, 32, 23]]
  
types = ['A', 'B',
         'C', 'D', ]
  
pyramid_chart = pygal.Pyramid()
  
# Naming the title
pyramid_chart.title = 'Pyramid Chart'
  
for type, dat in zip(types, data):
    pyramid_chart.add(type, dat)
  
pyramid_chart
