Actually i am looking for the way that set entire area as an hotspot , not just a data point , then i don't need to click a tiny weeny data point for drilling down to an other chart or trigger a js function .
If it supports this feature ,the xml would be like this :
<set value='29800' />
<set value='25800' />
<set value='26800' />
Is there any luck ? Or any plan about this feature ?
