I am always not sure if i've expressed myself correctly asking this
question, because it seems that there is an answer (just found it!). That's
a handler that treats the onmouse event, i.g. the event that fires when we
hover a point.
function handler (e){
alert ("in the handler");
var a, b;
a = data.getValue(e.row, 0);
b = data.getValue(e.row, 1);
alert('The user selected ' + a + ' ' + b + 'coordinates ')
}
Or is it the experimental API you were talking about?
