1) The problem is with the Override object here

for (int i = 0; i < GetHistogramData().Rows.Count; i++)
{
Override colorOverride = new Override();
colorOverride.Column = -2;
colorOverride.Row = i;
colorOverride.PE = new PaintElement(Color.LightSlateGray);
this.ultraChart1.Override.Add(colorOverride);
} 

what I want is that Line chart to be red collor and Column chart to be LightSlateGray. But when I use override for 

colorOverride.Column = 0;

colorOverride.Row = 0;

it colors first column of column chart and whole line chart in the same color. So when I get Override through the foreach loop all columns in the column chart (it is desirable) and whole line chart (not desirable) have the same color, colors are merged and it is impossible to see the line when columns are on the background.

Is there a way to set different color for the line?

I was trying to do something like this but it didn't helped

for (int i = 0; i < GetHistogramData().Rows.Count; i++)
{
Override colorOverrideline = new Override();
colorOverrideline.Column = -2;
colorOverrideline.Row = i;
colorOverrideline.PE = new PaintElement(Color.Red);
myLineLayer.ChartComponent.Override.Add(colorOverrideline);
}

It colors whole control anyway

I also checked ZeroAlignData property via designer. BTW where can I find this property in the code?

2) Also while using column chart in ultraChart1_FillSceneGraph event I was able to get var axisX = e.Grid["X"] as IAdvanceAxis; but now when I use composite chart I get null here.

The same thing with labels angle. When I was using column chart I was able to set Axis.X.Labels.Orientation = Custom and than set angle of labels. Using composite chart this property takes no effect.

Can you advice something?

Thanks!
