A candle chart displays stock information using High, Low, Open and Close values. The size of the wick line is determined by the High and Low values, while the size of the bar is determined by the Open and Close values. The bar is displayed using different colors, depending on whether the price of the stock has gone up or down.

Imports DataDynamics.ActiveReports.Chart.Graphics
With Me.ChartControl1.Series(0)
.Properties("BodyDownswingBackdrop") = New Chart.Graphics.Backdrop(Color.FromArgb(255, 192, 255))
.Properties("BodyUpswingBackdrop") = New Chart.Graphics.Backdrop(Color.FromArgb(192, 192, 255))
.Properties("WickLine") = New Chart.Graphics.Line(Color.Indigo)
.Properties("BodyWidth") = 7.0F
End With
// C#
Using DataDynamics.ActiveReports.Chart.Graphics
this.chartControl1.Series[0].Properties["BodyDownswingBackdrop"]= new Chart.Graphics.Backdrop
