I'm trying to customize the effect just like Google's. Look at here <http://www.yupoo.com/photos/view?id=ff80808117800d890117be8199b91699> to see the screen shot of Google's lineChart. The data item grow larger when mouse roll over it, rather than obey the default effect. How can i get it or by which interface can i get it? A green hand problem maybe, but thank you very much!
