B4J Code Snippet [PyBridge] Pygal - nice charting library

Pygal — pygal 2.0.0 documentation

This library produces interactive SVG, which can be loaded with WebView.
It has many features. Small example:

Dim PyGal As PyWrapper = Py.ImportModule("pygal")
Dim PyGalStyle As PyWrapper = Py.ImportModule("pygal.style")
Dim Chart As PyWrapper = PyGal.Run("StackedLine") _
    .ArgNamed("style", PyGalStyle.GetField("CleanStyle")).ArgNamed("fill", True).ArgNamed("interpolate", "cubic")
Chart.Run("add").Arg("A").Arg(Array(1, 3,  5, 16, 13, 3,  7))
Chart.Run("add").Arg("B").Arg(Array(5, 2,  3,  2,  5, 7, 17))
Chart.Run("add").Arg("C").Arg(Array(6, 10, 9,  7,  3, 1,  0))
Chart.Run("add").Arg("D").Arg(Array(2,  3, 5,  9, 12, 9,  5))
Chart.Run("add").Arg("E").Arg(Array(7,  4, 2,  1,  2, 10, 0))
'Chart.SetField("title", "This is the title") 'uncomment with BETA #3+
Wait For (Chart.Run("render").Fetch) Complete (Result As PyWrapper)
File.WriteBytes(xui.DefaultFolder, "temp.svg", Result.Value)
WebView1.LoadUrl(xui.FileUri(xui.DefaultFolder, "temp.svg"))

PyWrapper.SetField is a new method that will be added in the next beta.

Dependencies:
pip install pygal
