Hello

I made a XamDataChart using OlapFlatData for X-Axis. 

How can I control the expand icons? More specific I need to be able to:

- Set visibility, is there a way to hide them?

- Make sure the are always expanded. If I add another row to the flatdatasource the are default collapsed

I cannot find anywhere to control them, so I am hoping you can guide on where to find the settings. 

I´ve attached a screen so you exactly know what I am talking about.
