How to programaticaly set the panel range in Ninja?

In my indicator, it is a custom plot like in Ninja's custom plot example so the scale is not set automatically like with a normal plot.

In the indicator code i use:
this.ChartControl.FixedPanelMaxRight = highest + (highest/10);
this.ChartControl.FixedPanelMinRight = lowest - (lowest/10);

to set the min and max values and that works.

But when i try to set the Range Type
this.ChartControl.YAxisRangeTypeRight = YAxisRangeType.Fixed;

the range in the chartpanel is set instead of the panel the indicator is on.

How to set the range in a specific panel?

Also what is the correct way to update the chart with such changes?
Refresh?
Invalidate?
ChartControl.Update();

Any help is greatly appreciated.
