Hi, anyone know if is possible to draw a point on an existing chart as show in this picture (the green point is 'hand-made' ^^ ): img374.imageshack.us/my.php?image=plot2jd1.jpg

I would like to draw a point in a specific time istant (like the green at time=3) and for example, eventually, at time 4 delete the point at 3 and draw a new one.
Thanks to all
Federico.

You could either use an annotation on the chart (e.g. XYShapeAnnotation) or modify the renderer to draw a circle at a particular point.
