Now I have a problem with tooltip position, please see this link:http://jsfiddle.net/tannm/s5QX5/26/
when hovering on the flags which were set y higher than xaxis, the tooltip still stay at the bottom of the chart, is any one have any ideas to controlling the flag's tooltip position
the best solution is tooltip's position can be placing next to mouse's position.
I have research but have not an answer, like this topic viewtopic.php?f=12&t=12323&p=55555&hilit=tooltip+position#p55555
Thanks in advance.
