Specifying legend text at runtime

[drodriguez]

I would like to know how do I specify legend item text at runtime. When I bind a data object to a chart, it automatically binds the wrong data to the legend. I would like to have control over this.

Hi drodriguez,

To add a custom legend item you can use the following code snippet:

           Dim customLegendItem As Telerik.Charting.LabelItem
        customLegendItem = New Telerik.Charting.LabelItem()
        customLegendItem.TextBlock.Appearance.TextProperties.Font = New Font("Arial", 8)
        customLegendItem.Marker.Appearance.FillStyle.MainColor = Color.Blue
        customLegendItem.Marker.Appearance.FillStyle.FillType = Telerik.Charting.Styles.FillType.Solid
        customLegendItem.Marker.Appearance.Figure = "Diamond"
        customLegendItem.Marker.Appearance.Visible = True
        customLegendItem.TextBlock.Text = "  Custom Legend Item"

Eventually if the series name appears in the legend you have to set the LegendDisplayMode property of the series to Nothing. For example:

    Me.chart1.Series(0).Appearance.LegendDisplayMode =     Telerik.Charting.ChartSeriesLegendDisplayMode.Nothing
