You provide the size of the canvas when you create 
it normally. But you can use at least 2 approaches.

1) Given the fixed size of your canvas you can 
scale the graphs to fit - keeping track oof the 
longest X and Y measures and scaling against the corresponding
size of the canvas.

or

2) Scale the canvas to match the graphs.
If the canvas gets bigger than a certain size
(maybe related to screen size?) youi can add 
scroll bars.

HTH,

Alan G.
