Hello Dariogs,

Have you been able to resolve your issue ? Did you have a time to take a look at the attached sample. Please let me know if you have any questions.

Regards

Hi again,

Thanks for attached screenshots. Generally this behavior is expected, because our control try to drawn the lables in the most suitable place in the chart (depending of empty space, other elements, angle of rotation and so on). If you try to rotate or scalling your chart, you will see that these lables will change their possition in the chart area. Maybe one possible approach could be if you rotate your chart with few degrees.

Please let me know if you have any questions.

I know 2 months had passed from my last request, but just today I've been testing you suggestion, and with a small change it worked, but still having a issue.  I am attaching an image with my results to show you my problem. How do I do to positionate the labels in the top of each column, it looks like sometimes it works and sometimes it doesn't.

Here my code....

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

{

List<Text> TextList = new List<Text>();

TextList.Clear();

string IsAddedKey = null;

+ pr.Column.ToString()))

{

decimal value = pr.Value != null ? Convert.ToDecimal(pr.Value) : 0;

if (value > 0)

{

Text textLabel = new Text(new Point((int)((Infragistics.UltraChart.Core.Primitives.Path)(pr)).GraphicsPath.PathPoints[0].X, (int)((Infragistics.UltraChart.Core.Primitives.Path)(pr)).GraphicsPath.PathPoints[0].Y), value.ToString(), new Infragistics.UltraChart.Shared.Styles.LabelStyle(new Font("Arial", 8, FontStyle.Bold), Color.Black, true, true, true, StringAlignment.Center, StringAlignment.Center, Infragistics.UltraChart.Shared.Styles.TextOrientation.Horizontal));

textLabel.PE.Fill =

Color.FromArgb(51, 51, 51);

IsAddedKey = pr.Row.ToString() +

"-" + pr.Column.ToString();

TextList.Add(textLabel);

}

}

}

foreach (var item in TextList.Distinct())

 e.SceneGraph.Add(item);

}

Thanks for the feedback  Dario. If you have any questions, do not hesitate to write us.

Regards

Hello Anandraj,

anandraj said:

could you post similar example for vb.net

    Private Sub UltraChart1_FillSceneGraph(sender As System.Object, e As Infragistics.UltraChart.Shared.Events.FillSceneGraphEventArgs) Handles UltraChart1.FillSceneGraph
        TextList.Clear()
        Dim IsAddedKey As String = Nothing
        For Each pr As Primitive In e.SceneGraph
            If pr.Row <> -1 AndAlso pr.Column <> -1 AndAlso IsAddedKey <> (pr.Row.ToString() + "-" + pr.Column.ToString()) Then
                Dim tempPercent As Decimal = (Convert.ToDecimal(pr.Value) / CalcSum(dt.Rows(pr.Row))) * 100
                Dim textLable As New Text(New Point(CInt(DirectCast(pr, Infragistics.UltraChart.Core.Primitives.Path).GraphicsPath.PathPoints(0).X), CInt(DirectCast(pr, Infragistics.UltraChart.Core.Primitives.Path).GraphicsPath.PathPoints(0).Y)), tempPercent.ToString("0.00") + " %")
                textLable.PE.Fill = Color.Black
                IsAddedKey = pr.Row.ToString() + "-" + pr.Column.ToString()
                TextList.Add(textLable)
            End If
        Next
        For Each item As Text In TextList.Distinct()
            e.SceneGraph.Add(item)
        Next
    End Sub

I will try the example and let you know.

Thanks

Dario
