Problems with Category Bar Properties

[User (Legacy)]

Hello! I'm working with chart Fx for .net 6.2 and OLAP extension.

I'm having problems using some properties of the Category Bar. For example, 

I'm trying to set the property Visible to false as it comes in the 

Documentation, but it just doesn't work, it doesn't give any error, but the 

Category bar still shows on the screen. I've tried make it work placing the 

following code in many places but without results

CategoryBar cb = (CategoryBar) Olap1.AnalysisObject;

cb.Visible = false;

any ideas?

thank you
