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:
# 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:
# 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:
# 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
