How to get the datasource information from Kendo UI dragend event? - kendo-ui

Question

This is the code for the line chart which has drag function to highlight some data. I would like to get the datasource information in the dragEnd event,currently I am just getting screenX and screenY values.
function createChart(data) {
$("#TimeSeriesPlot").kendoChart({
title: {
text: series_name.toUpperCase()
},
dataSource :{
data:data.timeseries,
},
series: [{
type: "line",
field:"v",
categoryField:"ts",
}],
valueAxis: {
labels: {
format: "{0}"
},title:{
text: "value"
},
line: {
visible: false
},
},
categoryAxis: {
labels: {
type: "date",
},
tooltip: {
visible: true,
// shared:true,
template: "${category} - ${value}"
},
plotAreaClick: onPlotAreaClick,
seriesClick:onSeriesClick ,
dragStart:onDragStart ,
drag:onDrag,
dragEnd:onDragEnd
});
}
}
function onSeriesHover(e) {
console.log(kendo.format("Series hover :: {0} ({1}): {2}",
e.series.name, e.category, e.value));
}
function onSeriesClick(e){
// console.log(selected_anamolies);
// console.log(e.category);
selected_anamolies.push("ts",e.category);
selected_anamolies.push("v",e.value);
}
function onDragStart(e){
// console.log("dragstart"+e.axisRanges.ts);
// console.log("dragstart"+e.sender._highlight._points[0].value);
// console.log("dragstart"+e.sender._highlight._points[0].category);
}
function onDrag(e){
var Rect = kendo.geometry.Rect;
var draw = kendo.drawing;
prevloc=e.originalEvent.x.startLocation;
currentloc=e.originalEvent.x.location;
var rect=new Rect([prevloc,50],[currentloc-prevloc,150]);
var path = draw.Path.fromRect(rect,{ stroke: null,fill:{color:"#d3f1fb",opacity:0.2}});
var chart = e.sender;
// var surface = draw.Surface.create($("#surface"));
chart.surface.draw(path);
//
}
function onDragEnd(e){
console.log(dragEnd)
}
