Using Methods like getItem and getItemIndex
posted

Is there any example showing how to use methods like 'getItem' and 'getItemIndex' in igDataChart. On this page http://help.infragistics.com/jQuery/2013.1/ui.igDataChart only method signature is shown.

ACTUALLY, I'M TRYING TO FIND WHICH DATA-POINT IS CLICKED, SINCE THERE IS NO EVENT OR METHOD AVAILABLE FOR DATA-POINT CLICK, I TRIED USING SERIES EVENTS.

I tried using the method getItemIndexFromSeriesPixel as below,

//On Series Mouse left Button Up, call logSeriesClick

seriesMouseLeftButtonUp: function (event, args) { logSeriesClick(event, args); },

//Using the mouse position, get the item beneath it.

function logSeriesClick(event, args) { 

var xPos = Math.round(args.positionX * 10) / 10;
var yPos = Math.round(args.positionY * 10) / 10
logEvent('Series MouseUp (x, y): ' + xPos + ", " + yPos);
var item = chart.igDataChart("getItemIndexFromSeriesPixel", "series1", { x: xPos, y: yPos });
logEvent(item);

}

But I'm unable to get any index, the 'item' variable is always having the chart object.
