How to show or hide labels in Pygal?

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 show/hide the label value of the plot window in the Pygal module. Here are various ways to change the default show/hide labels as per our requirement.

Approach:

• Import required module.
• Create a chart object.
• Show or hide label value.
• 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
# enable/disable labels
chart = pygal.Bar(show_x_labels=False)

# 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('aa.png')

Output

Example 2:

Python3

# import library
import pygal

# enable/disable labels
chart = pygal.Line(show_y_labels=False, show_x_labels=True)

# X-label
chart.x_labels = 'Point 1', 'Point 2', 'Point 3'
# y-label
chart.add('line', [.0002, .0005, .00035])

# naming the title
chart.title = 'Line Chart'

chart.render_to_png('aa.png')

Output

Example 3:

Python3

# import library
import pygal
import numpy

# creating the chart object
# enable/disable labels
chart = pygal.HorizontalBar(show_x_labels=True, show_y_labels=True)

# 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 = 'HorizontalBar Chart'

chart.render_to_png('aa.png')

Output
