Yahoo recently released a new charting system that’s in beta. When it was originally released it didn’t work in IE7, but that’s been fixed. The charts are really nice, and integrate in well with their existing portfolio on My Yahoo.
On a side note, as the chart above shows, the Dow is now higher than it’s ever been, it broke the high water mark set back in 1999 about a month ago. It shot up 110 points today and crossed 12,100 point for the very first time.
