Perspectives - PowerChart - delete rangeBrush.values

I'm on 8.1.45

I want to customize the Powerchart menu, I face and issue with the deletion of rangeBrush values.

For the XTrace deletions works well, I just assign an empty array to the interaction.xTrace.values and all is done.

But with rangeBrush even I resset the interraction.rangeBrush.values all ranges stay on screen.

Anyone can help me with that ?
