I'm trying to adjust the X Extent of one of our charts in order to provide some margin between the X-axis labels and the bottom of the control/form.

Here's the code I'm using to adjust the intent.

<code snippet>
Dim xAxisClipBehavior As New ClipTextAxisLabelLayoutBehavior
xAxisClipBehavior.ClipText = True
xAxisClipBehavior.Enabled = True
xAxisClipBehavior.EnableRollback = True
xAxisClipBehavior.HideText = False
xAxisClipBehavior.Trimming = StringTrimming.EllipsisCharacter
xAxisClipBehavior.UseOnlyToPreventCollisions = False

chtStatsChart.Axis.X.Labels.Layout.Behavior = AxisLabelLayoutBehaviors.UseCollection
chtStatsChart.Axis.X.Labels.Layout.BehaviorCollection.Clear()
chtStatsChart.Axis.X.Labels.Layout.BehaviorCollection.Add(xAxisClipBehavior)

chtStatsChart.Axis.X.Extent = chtStatsChart.Axis.X.Extent + 80
</code snippet>

This works fine on my machine and I get the expected results.  However on some of my co-workers machines, there is still no bottom margin and some of the x-axis labels are even being cut off.

Here are some screenshots to show examples.

This screenshot is from my machine - you can see it's working:

This is a screenshot from a teammates system - obviously it's not working there:

 I'm not sure why it's working on my system and not on others....any thoughts?

Any assistance would be appreciated!
