ZedGraph - How to display the cursor at the point x, y without using the mouse?

I draw a curve in Zedgraph as follows:

GraphPane myPane = zgc.GraphPane;
PointPairList list1 = new PointPairList();
for(int i =0; i<10; i++)
    list1.Add(i,i);            
LineItem myCurve = myPane.AddCurve("Title",
          list1, Color.Red, SymbolType.None);        

zgc.AxisChange();
zgc.Refresh();

How can I display the cursor (or any other graphic) at a specific point x, yon myCurveas follows:

SetCursor(myCurve, list1[3]);

Knowing the specific point of your curve, you can use GraphPane.GeneralTransform(...)method

So using the following code:

var myPoint = myCurve[3];
var screenPoint = myPane.GeneralTransform(myPoint.X, myPoint.Y, CoordType.AxisXYScale);

will give you the coordinates converted to a specific point on the screen (in pixels).

Then you need to find a higher level method (possibly in Windows forms ...) that will move your cursor to that point.
