📊 ChartMaker 📶
SeleniumBase ChartMaker lets you use Python to generate HTML charts.
(Click to see a presentation with multiple charts)
Here’s how to run a simple pie chart presentation from GitHub => seleniumbase/SeleniumBase/examples/chart_maker:
cd examples/chart_maker
pytest my_chart.py
Here’s the code for that pie chart presentation (GitHub => seleniumbase/SeleniumBase/examples/chart_maker/my_chart.py):
from seleniumbase import BaseCase
BaseCase.main(__name__, __file__)
class MyChartMakerClass(BaseCase):
def test_chart_maker(self):
self.create_presentation()
self.create_pie_chart(title="Automated Tests")
self.add_data_point("Passed", 7, color="#95d96f")
self.add_data_point("Untested", 2, color="#eaeaea")
self.add_data_point("Failed", 1, color="#f1888f")
self.add_slide("<p>Pie Chart</p>" + self.extract_chart())
self.begin_presentation(filename="my_chart.html")
Here’s how to run an example presentation with multiple charts:
cd examples/chart_maker
pytest chart_presentation.py
Here are screenshots from the examples:
Here's a line chart example:
from seleniumbase import BaseCase
BaseCase.main(__name__, __file__)
class MyChartMakerClass(BaseCase):
def test_chart_maker(self):
self.create_presentation()
self.create_line_chart(
title="Time Outside", subtitle="Last Week", unit="Minutes")
self.add_data_point("Sun", 5)
self.add_data_point("Mon", 10)
self.add_data_point("Tue", 20)
self.add_data_point("Wed", 40)
self.add_data_point("Thu", 80)
self.add_data_point("Fri", 65)
self.add_data_point("Sat", 50)
self.add_slide("<p>Line Chart</p>" + self.extract_chart())
self.begin_presentation(filename="line_chart.html", interval=8)
This example is from test_line_chart.py, which you can run from the examples/chart_maker folder with the following command:
pytest test_line_chart.py
Because that presentation above has an interval set to 8, it will automatically advance to the next slide after 8 seconds. (Or exit if there are no more slides.)
For a more advanced example (multiple charts in a presentation):
from seleniumbase import BaseCase
BaseCase.main(__name__, __file__)
class MyChartMakerClass(BaseCase):
def test_chart_maker_presentation(self):
self.create_presentation(theme="sky")
self.create_pie_chart(title="Automated Tests")
self.add_data_point("Passed", 7, color="#95d96f")
self.add_data_point("Untested", 2, color="#eaeaea")
self.add_data_point("Failed", 1, color="#f1888f")
self.add_slide("<p>Pie Chart</p>" + self.extract_chart())
self.create_bar_chart(title="Language")
self.add_data_point("Python", 33, color="Orange")
self.add_data_point("JavaScript", 27, color="Teal")
self.add_data_point("HTML + CSS", 21, color="Purple")
self.add_slide("<p>Bar Chart</p>" + self.extract_chart())
self.create_column_chart(title="Colors")
self.add_data_point("Red", 10, color="Red")
self.add_data_point("Green", 25, color="Green")
self.add_data_point("Blue", 15, color="Blue")
self.add_slide("<p>Column Chart</p>" + self.extract_chart())
self.create_line_chart(title="Last Week's Data")
self.add_data_point("Sun", 5)
self.add_data_point("Mon", 10)
self.add_data_point("Tue", 20)
self.add_data_point("Wed", 40)
self.add_data_point("Thu", 80)
self.add_data_point("Fri", 65)
self.add_data_point("Sat", 50)
self.add_slide("<p>Line Chart</p>" + self.extract_chart())
self.begin_presentation(filename="chart_presentation.html")
Here’s how to run that example:
cd examples/chart_maker
pytest chart_presentation.py
