your description is very general.
What it is you want to show?
The current x,y value?
That is apoint, you don't need a graph for that.
Or do you want to show a "moving" graph as time passes?
Explain with a bit more details what it is you are trying to do, what have you done (post code), and then we can see if we can help you more.
