Hi,

I have a StackBarChart and the Y axis are long (approx 50 characters). I have used WrapTextAxisLabelLayoutBehavior to wrap the Y axis labels over two lines.

The problem I have is that the labels are clipped at the top and bottom. Is it possible to change the height of a label?

Any help greatly appreciated.

Regards

James O'Doherty

This appears to be a problem when the series labels are horizontally oriented and there's a wrap behavior defined. However, you can implement a quick fix by handling the chart's FillSceneGraph event:

Private Sub UltraChart1_FillSceneGraph(ByVal sender As System.Object, ByVal e As FillSceneGraphEventArgs) Handles UltraChart1.FillSceneGraph
   For Each p As Primitive In e.SceneGraph
      If TypeOf (p) Is Text Then
         Dim label As Text = CType(p, Text)
         If label.Path Is Nothing Then Return
         If label.Path.IndexOf("Border.Title.Grid.Y") = -1 Then Return
         label.bounds.Height = 40
      End If
   Next
End Sub

Hi Max,

Thanks for the reply.

Here's a screenshot.

Here's the code

                                    .Axis.Y.Labels.SeriesLabels.Orientation = Infragistics.UltraChart.Shared.Styles.TextOrientation.Horizontal
                                    .Axis.Y.Labels.SeriesLabels.HorizontalAlign = StringAlignment.Far
                                    .Axis.Y.Labels.SeriesLabels.VerticalAlign = StringAlignment.Center
 
                                    .Axis.Y.Labels.SeriesLabels.Layout.Behavior = Infragistics.UltraChart.Shared.Styles.AxisLabelLayoutBehaviors.UseCollection
 
                                    Dim behavior = New Infragistics.UltraChart.Resources.Appearance.WrapTextAxisLabelLayoutBehavior()
                                    behavior.Enabled = True
                                    behavior.EnableRollback = False
                                    behavior.UseOnlyToPreventCollisions = False
 
                                    .Axis.Y.Labels.SeriesLabels.Layout.BehaviorCollection.Add(behavior)
 
                                    .Axis.X.Extent = 30
                                    .Axis.Y.Extent = 120

I wonder if you need to increase chart.Axis.Y.Extent to accomodate the extra space. You might also want to try setting EnableRollback to false on your layout behavior. Can you provide a screenshot?
