Pointer moves along with mouse in Chart

Hi,

I have seen one graph in http://www.bseindia.com/.
How to make that graph. That was very interesting to watch.
And seen One Dash Board in http://www.bseindia.com/SensexView/SensexView.aspx
this is also so nice that shows message box like validation input message.

Can we create in excel also?
Please if possible send one sample and explain us how to make...

Thanks...
