[jQuery] Help with google chart

I want to scale the line graph according to the maxvalue and the
minvalue so that the graph is appropriate with respect to scale. Any
help how can I do this.
I mean if the maxvalue is 10 and minvalue is 0 then I want the graph
range to be 0-10 and not 0-100 which it is present(thats my
interpretation correct me if I am wrong)
Please Help,
Thanx
