Changing the highligt color on 3D pie chart
posted

Hello,

 I am trying to change the highlight color on the pieces of a 3d pie chart.  I see where you can change the color to a certian color but what I am trying to do is change the color of the pie piece to a light color of the pie pieces color.  Similar to what Control.Light.Light would to a control.

 The other thing that has me a little stumped is I would like to do is only highlight the pie chart piece on a mouse click and not a hover. 

Any help is great.

 Thanks,

Mike

    i recommend just setting the chart's Tooltips.Display property to Never and doing the highlighting in code in a ChartDataClicked event handler.  here's one solution which does this using a CustomLinear ColorModel and replacing the appropriate color whenever a slice is clicked:

    using Infragistics.UltraChart.Shared.Events;

    using Infragistics.UltraChart.Shared.Styles; 

    private Color[ _Colors = new Color[ { Color.Red, Color.Green, Color.Blue };
    private Color[ _LightColors = new Color[ { Color.Pink, Color.Lime, Color.SkyBlue };
    private void Form1_Load(object sender, EventArgs e)
    {
        this.ultraChart1.ColorModel.ModelStyle = ColorModels.CustomLinear;
        this.ultraChart1.ColorModel.CustomPalette = this._Colors;
    }

    private void ultraChart1_ChartDataClicked(object sender, ChartDataEventArgs e)
    {
        Color[ newColors = new Color[this._Colors.Length];
        this._Colors.CopyTo(newColors, 0);
        newColors[e.DataRow] = this._LightColors[e.DataRow];
        this.ultraChart1.ColorModel.CustomPalette = newColors;
    }
