My chart draws a CartesianCustomAnnotation showing an ellipse that is meant to skirt up the curve in my profile line I bind the annotation's HorizontalValue and VerticalValue properties to the center point of the ellipse. I've attached an image to show what it looks like.
The problem is that if my profile curve is gradual, the ellipse gets so big that it the center point is actually outside of the chart axis Minimum/Maximum values. As soon my annotation's HorizontalValue or VerticalValue is outside the boundaries, the chart stops drawing it at all. Even if its radius means that it *would*, in fact show up in part on the display (which is what I want).
Is there a way to force the chart to draw my annotation regardless of where its origin lies?
