pygal.Line () substantially single-line
identical pattern pygal.StackedLine (fill = True), but having a filling and stacking values render
view.x_labels = map (str, range ( 1,34)) provided x-axis range
1, single family
. 1 Import pygal 2 . 3 Frequency = [10, 20 is, 30, 40, 50, 60 ] . 4 bar = pygal.Bar () # create a histogram of the object is instantiated . 5 bar.title = ' Test ' # Set Title . 6 bar = .x_labels [ ' . 1 ' , ' 2 ' , ' . 3 ' , ' . 4 ' , ' . 5 ' , ' . 6 ' ] // the value of the x-axis . 7 bar.x_title = " the Result " // Set the name of the x-axis . 8 bar.y_title = " Frequency of the Result " . 9 bar.add ( ' D ' , Frequency) 10 bar.render_to_file ( ' bar_chart.svg ' ) # save the image as SVG file, through the browser View
result:
2, making multi-family icon
. 1 Import pygal 2 . 3 View = pygal.Bar () . 4 view.add ( ' Orange ' , [0,1,3,4,6,7,8,9,11,22 ]) . 5 view.add ( ' Banana ' , [1,2,3,4,4,5,6,6,7,16,17 ]) . 6 view.render_in_browser () // render to the browser
3, stacked charts StackedBar
1 import pygal 2 3 bar_chart = pygal.StackedBar() 4 bar_chart.add('Fibonacci', [0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55]) 5 bar_chart.add('Padovan', [1, 1, 1, 2, 2, 3, 4, 5, 7, 9, 12]) 6 bar_chart.render_to_file("StackedBar.svg")
