How to change number of scales in pygal?
Prerequisites:pygal
Pygal is a Python module that is mainly used to build SVG (Scalar Vector Graphics) graphs and charts. Pygal is a graphics and user interface library for Python that provides functionality commonly required in designing and science applications.
Â
In this article, we will see how we can change the number of scales in pygal. A scale on the graph shows the way the numbers or pictures are used in data. The scale selected for a graph axis has a significant impact on how the audience interprets the message and is an important part of optimizing data visualization. Thus, a scale plays a crucial part in plotting graphs.
Approach
- Import required module.
- Create a chart object.
- Pass maximum/minimum number of scale.
- Label the graph.
- Display Graph.
Syntax:
- min_scaleÂ
- max_scale
You can specify the maximum/minimum number of scale graduation to generate with auto-scaling if possible.
Example 1:
Python3
# importing pygal import pygal import numpy     # creating the chart object # minimum number of scale chart = pygal.Line(min_scale=40)   # Random data chart.add('line', [0, .02, .05, .0035])   # naming the title chart.title = 'Line Chart'  chart.render_to_png('aa.png') |
Output
Example 2:
Python3
# importing pygal import pygal import numpy     # creating the chart object # maximum number of scale chart = pygal.Line(max_scale=3)   # Random data chart.add('line', [0, .02, .05, .0035])   # naming the title chart.title = 'Line Chart'  chart.render_to_png('aa.png') |
Output
