Line chart in Pygal - GeeksforGeeks

Last Updated : 10 Jul, 2020

A

or

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.

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.

line_chart = pygal.Line()

# 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

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.

line_chart = pygal.HorizontalLine()

# 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))
