Pygal is a Python module that is mainly used to build SVG (Scalar Vector Graphics) graphs and charts. SVG is a vector-based graphics in the XML format that can be edited in any editor. Pygal can create graphs with minimal lines of code that can be easy to understand and write.
Pygal is the Python module which provides 14-built in styles under the pygal.style class which are as follows:
- DarkStyle
- NeonStyle
- DarkSolarizedStyle
- LightSolarizedStyle
- LightStyle
- CleanStyle
- RedBlueStyle
- DarkColorizedStyle
- LightColorizedStyle
- TurquoiseStyle
- LightGreenStyle
- DarkGreenStyle
- DarkGreenBlueStyle
- BlueStyle
Note: Any graph can be styled using these style by passing the style name in the style argument.
Example 1: Styling Funnel graph
Python3
# importing pygal import pygal from pygal.style import NeonStyle # creating the chart object funnel = pygal.Funnel(style = NeonStyle) # naming the title funnel.title = 'Funnel' # Random data funnel.add('A', [26, 22, 39, 39, 32, 30, 33, 24, 24, 30]) funnel.add('B', [31, 40, None, None, None, None, 40, 32, 25, 31]) funnel.add('C', [37, 27, 31, 20, None, 32, 24, 39, 29, 22]) funnel.add('D', [38, None, 20, 29, 33, 23, 32, 33, 32, 23]) funnel |
Output:
Example 2: Styling Stacked Line Chart
Python3
# importing pygal import pygal from pygal.style import LightSolarizedStyle # creating the chart object line = pygal.StackedLine(fill = True, style = LightSolarizedStyle) # naming the title line.title = 'Stacked Line' # Random data line.add('A', [26, 22, 39, 39, 32, 30, 33, 24, 24, 30]) line.add('B', [31, 40, None, None, None, None, 40, 32, 25, 31]) line.add('C', [37, 27, 31, 20, None, 32, 24, 39, 29, 22]) line.add('D', [38, None, 20, 29, 33, 23, 32, 33, 32, 23]) line |
Output:
Example 3: Styling Bar Chart
Python3
# importing pygal import pygal from pygal.style import BlueStyle # creating the chart object bar = pygal.Bar(fill = True, style = BlueStyle) # naming the title bar.title = 'Bar Chart' # Random data bar.add('A', [26, 22, 39, 39, 32, 30, 33, 24, 24, 30]) bar.add('B', [31, 40, None, None, None, None, 40, 32, 25, 31]) bar.add('C', [37, 27, 31, 20, None, 32, 24, 39, 29, 22]) bar.add('D', [38, None, 20, 29, 33, 23, 32, 33, 32, 23]) bar |
