Spotfire: How to create Chart Categorical expression with Display Name? (C#, IronPython)

 Example of Categorical Expression with Display Name

This works:

$"<LandQuality{duration} as [Land Quality]>"


This doesn't work:

$"<LandQuality{duration}>  as [Land Quality]"


Example:

BarChart.XAxis.Expression = $"<LandQuality{duration} as [Land Quality]>";


Let's compare this to Continuous Expression


BarChart.XAxis.Expression = $"[LandQuality{duration}] as [Land Quality]";

While working with WPF Visual Tree, one of the common tasks is to find the Parent(Ancestor) or Child of any specific element (DependencyObject).
