Sample code

This example adds the dataset to any Chart (Desktop, Mobile or Web) control that has its type set to Doughnut:

Var sales() As Double = Array(345890.0, 421934, 456908, 567987)
Var colors() As Color = Array(Color.Red, Color.Green, Color.Yellow, Color.Blue)
Var ds As New ChartCircularDataset("Sales", sales, Colors)
Me.AddDataset(ds)
Me.AddLabels("Q1", "Q2", "Q3", "Q4")
