Need dimensions value on in VIZ bar Chart dataselect event.

Hi All

How can I get the dimension value in VIZ bar Chart on dataselect event.

Clicked on PCV_Warning bar then I need PCV_Warning text in alert message.

I have used following code for BAR generation.

var oDataset1 = new sap.viz.ui5.data.FlattenedDataset({

dimensions : [

{

axis : 1, // must be one for the x-axis, 2 for y-axis

name : 'EventID',

value : "{EventID}"

}

],

measures : [

{

name : 'NumofInstances', // 'name' is used as label in the Legend

value : '{NumofInstances}' // 'value' defines the binding for the displayed value

}

],

data : { path : "/Rowset/Row" }

});

oChart1= new sap.viz.ui5.Bar(

{

width : "600px",

height : "350px",

plotArea : {

//'colorPalette' : d3.scale.category20().range()

},

title : {

visible : true,

text : 'Bar Chart'

},

selectData : [ function(oEvent) {

alert('hi'+oEvent.getSource());

}, this ],

dataset : oDataset1

});

Thanks in advance
