Line chart in Pygal
  • Last Updated : 10 Jul, 2020

A line chart or line graph is a type of chart which helps to displays the information as a series of all data points called ‘markers’ and those markers are connected straight through line segments. It is a basic type of chart common in many fields which shows ascending or descending in a graph. A line chart is often used to visualize a trend in data over intervals of time which helps to represent the graph more effectively. Dimensions in the data are often displayed on the x-axis and y-axis.

Creating Line Chart

1) Simple Line Chart: Simple basic line graphs are used for showing the relationship between two variables in vertical form. Line() method is used to create simple line graphs in Pygal.

Syntax:

line_chart = pygal.Line()

Example:




# importing pygal
import pygal
import numpy
  
  
# creating line chart object
line_chart = pygal.Line()
  
# naming the title
line_chart.title = 'Line chart'
  
  
# adding lines
line_chart.add('A', numpy.random.rand(5))
line_chart.add('B', numpy.random.rand(5))
line_chart.add('C', numpy.random.rand(5))
line_chart.add('D', numpy.random.rand(5))
  
line_chart

Output:



2) Horizontal line chart: Horizontal line graph is the same as a basic line graph but the difference is it shows line horizontally from x-axis to y-axis. Both the variables are shown horizontally.

Syntax:

line_chart = pygal.HorizontalLine()

Example:




# importing pygal
import pygal
import numpy
  
  
# creating line chart object
line_chart = pygal.HorizontalLine()
  
# naming the title
line_chart.title = 'Horizontal Line chart'
  
  
# adding lines
line_chart.add('A', numpy.random.rand(5))
line_chart.add('B', numpy.random.rand(5))
line_chart.add('C', numpy.random.rand(5))
line_chart.add('D', numpy.random.rand(5))
  
line_chart

Output:
