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' ) |
