Change the color of one Point in a Scatterchart
posted

Hello,

 got two Questions

1) Is it possible to change the color from one specific Point in a Scatterchart?

2) How can I format the content of the Labels I have when I move with the mouse over a Point in my Scatterchart? (numeric Format ###,###,###,##0.00 is what I would need) 

Thanks in advance for your help

    HI Stefan,

    you can try code like this:

    protected void Page_Load(object sender, EventArgs e)

    {

    this.UltraChart1.Data.DataSource = DemoTable.Table();

    this.UltraChart1.DataBind();

    this.UltraChart1.Tooltips.FormatString = "<DATA_VALUE:###,###,###,##0.00>";

    this.UltraChart1.FillSceneGraph += new Infragistics.UltraChart.Shared.Events.FillSceneGraphEventHandler(UltraChart1_FillSceneGraph);

    }

    void UltraChart1_FillSceneGraph(object sender, Infragistics.UltraChart.Shared.Events.FillSceneGraphEventArgs e)

    {

    foreach (Primitive primitive in e.SceneGraph)

    {

    PointSet pointSet = primitive as PointSet;

    if (pointSet == null)

    {

    continue;

    }

    // you should find the right point in the pointSet.points collection

    DataPoint dataPoint = pointSet.points[0];

    Symbol symbol = new Symbol(dataPoint.point, pointSet.icon, pointSet.iconSize);

    symbol.PE.Fill = Color.Red;

    e.SceneGraph.Add(symbol);

    break;

    }

    }
