updating xy graph with the last point different

I want to display a simulation of the path of a rolling ball as updating xy graph.
The actual last point of the plot should be different from the older points, I imagine e.g.a thick circle.
The coordinates of the points I hold in two arrays, so I need a xy graph,
when I used xy chart buffer to get un updating graph all points of the plot are displayed in the same way, stars, circles and so on.

Hi,

Do you mean you want to display only one (or a known number) point at a time on the graph ?

Hi Titou
I want to display the old points for examample as a grey line
and the last the updating point as a red circle
So imagine to get a wandering red thick point with a grey tail

Ok, so the solution is coming from what you've just said. One plot for the old positions I assume you want to display a certain number of points... e.g. the last 10positions and one plot for the current ball position.

Tell me if this is ok...
