Can I change the highlight color for chart data?

[Administrator]

I find the highlight color to be too dark. It is possible to have a lighter color for the highlight effect?

TIA

Hi,

The Highlight color is controlled by the HightlightInterior property of a point style. You can modify the Highlight interior for each point by setting the Style.HighlightInterior:

Approach 1:

Set the HighlightInterior for each point style. If a series has 10 points, you need to set the style for all 10 point styles

VB.NET:

Dim highlightColor As BrushInfo = New BrushInfo(Color.LightBlue)
seriesCount.Styles(0).HighlightInterior = highlightColor
seriesCount.Styles(1).HighlightInterior = highlightColor
seriesCount.Styles(2).HighlightInterior = highlightColor
seriesCount.Styles(3).HighlightInterior = highlightColor
seriesCount.Styles(4).HighlightInterior = highlightColor
seriesCount.Styles(5).HighlightInterior = highlightColor
seriesCount.Styles(6).HighlightInterior = highlightColor
seriesCount.Styles(7).HighlightInterior = highlightColor
seriesCount.Styles(8).HighlightInterior = highlightColor
seriesCount.Styles(9).HighlightInterior = highlightColor

Approach 2 (Recommended):

Use the callback approach

AddHandler seriesCount.PrepareStyle, AddressOf Me.ChartControlSeries_PrepareStyle

Protected Sub ChartControlSeries_PrepareStyle(ByVal sender As Object, ByVal args As ChartPrepareStyleInfoEventArgs)
'' Style formatting using a callback. You can apply the same settings directly on the series style on the
'' point styles.
Dim series As ChartSeries = sender
Dim rand As New Random()
If Not (series Is Nothing) Then
args.Style.HighlightInterior = New BrushInfo(Color.LightBlue)
args.Handled = True
End If
End Sub

Thanks,

Davis
