Fairly neat, the label hovers seem to be particularly erratic, otherwise it looks rather nice.

I agree it looks really nice. I just wish someone would build one of these that was library-agnostic. It used to be that everything was self-contained, but nowadays there’s a lot of duplicate effort from various people building the same thing on top of every javascript toolkit, and if you happen to use a toolkit that isn’t prototype or jquery, your choices in javascript libraries quickly dwindle.

This one’s library agnostic :)

What engine are better use for drawing candles (high-low bars)? Preferably using jQuery or Flash.
