Sounds cool but currently we can only support JPG/PNG graphics using the BetterTouchFramework this is build on.

You could use the Google chart API:

I like the idea but how would you see this working, as far as the amount of space and showing price.. or are you thinking it's a mode? If the button could automatically rotate between price and sparkline that would be cool too.
