Note: I have just remaned my columns:

Z                     X                  Y

It's working Know.

I just want to clarify 2 points: (DataBind, and spaces is the solution below the best way for doing it?)

If I use the dataBind, I will not obtain the Design effect we need, so I droped the two line below,

UltraChart1.Data.DataSource = ds;

UltraChart1.Data.DataBind();

And I replace Them by: (but if I want to view ma labels clearly, I would add some spaces after the text Label    zVal + "     ",     if not the circle Icon will be on it)

 for (int i = 0; i < tbl.Rows.Count; i++)

{

DataRow myRow = tbl.Rows[i];

double xVal = Convert.ToInt32(myRow["X"]);

double yVal = Convert.ToInt32(myRow["Y"]);

string zVal = myRow["Z"].ToString();

xySeries.Points.Add(

 }

with out adding spaces to labels: xySeries.Points.Add(new XYDataPoint(xVal, yVal, zVal, false));

After adding spaces:

xySeries.Points.Add(new XYDataPoint(xVal, yVal, zVal + "     ", false));

Tks for the Help.

Let me know if you need more assistance regarding this.

Hello Zakia ,

The FillSceneGraph event is used to add/remove Primitives to/from your chart before the chart is rendered.

You should add the appearance before this phase.

You can use the Load method of the UltraChart

    protected void UltraChart1_Load(object sender, EventArgs e)

    {

        XYSeries xySeries = new XYSeries();

        // Add data points

        xySeries.Points.Add(new XYDataPoint(15, 20, "T1", false));

        xySeries.Points.Add(new XYDataPoint(30, 35, "T2", false));

        xySeries.Points.Add(new XYDataPoint(50, 30, "T3", false));

        xySeries.Points.Add(new XYDataPoint(60, 65, "T4", false));

        xySeries.Points.Add(new XYDataPoint(35, 25, "T5", false));

        xySeries.Points.Add(new XYDataPoint(80, 39, "T6", false));

        xySeries.Points.Add(new XYDataPoint(90, 45, "T7", false));

        xySeries.Points.Add(new XYDataPoint(40, 65, "T8", false));

        xySeries.Points.Add(new XYDataPoint(35, 80, "T9", false));

        xySeries.PEs.Add(new PaintElement(Color.Black));

        this.UltraChart1.Series.Add(xySeries);    

        ScatterChartAppearance appearance = new ScatterChartAppearance();

        ChartTextAppearance chartText = new ChartTextAppearance();

        chartText.Row = -2;

        chartText.Column = -2;

        chartText.ItemFormatString = "<ITEM_LABEL>";

        chartText.Visible = true;

        appearance.ChartText.Add(chartText);

        appearance.Icon = SymbolIcon.Circle;

        appearance.IconSize = SymbolIconSize.Small;

        UltraChart1.ScatterChart.ChartText.Add(chartText);

        this.UltraChart1.CompositeChart.ChartLayers[0].Series.Add(xySeries);

        this.UltraChart1.CompositeChart.ChartLayers[0].ChartTypeAppearance = appearance;    

    }

Hi,

I inserted the lines in the UltraChart1_FillSceneGraph, but it does not work, so where shall I put the code?

Thanks.
