Question

I wonder, is it possible to create vertical marker in zedgraph?
I want to render all chart points and make vertical marker as indicator of current position.

Answer 1

On a previous project, I used the following code to get that kind of effect.

int i = myPane.AddYAxis("");
myPane.YAxisList[i].Color = Color.Orange;
myPane.YAxisList[i].Scale.IsVisible = false;
myPane.YAxisList[i].MajorTic.IsAllTics = false;
myPane.YAxisList[i].MinorTic.IsAllTics = false;
myPane.YAxisList[i].Cross = pointOnXAxisThatIWantToMark;

In this case I add two axis to mark certain limits on my graph.
