Thanks for the reply. I have tried it out.
The additinal vertical axis is defined like this:
"Rate (nmol cm-3 s-1)"
On the image attached you can see some rectangles on the graph.
Before these rectangles used the main horizontal Axis(and now they are going to use the additional vertical axis). They are defined in the code behind like below:
CartesianMarkedZoneAnnotation ann =
ann.HorizontalFrom = areaData.X1;
ann.HorizontalTo = areaData.X3;
ann.VerticalFrom = areaData.Y3;
ann.VerticalTo = areaData.Y1;
ann.Fill = Brushes.ForestGreen;
ann.Opacity = 0.4;
Dont know if this is a stupid question :) But how would i apply the above additional vertical axis to these rectangles(CartesianMarkedZoneAnnotation)?
I cant do this 'ann.HorizontalAxis = additionalAxis' because the compiler cannot resolve the symbol 'additionalAxis'.
