Tooltip Template Formating in Kendo-UI

问题:

I have the following code, and initially my data consists only x and y values, however, once I added another value which is k but it stopped working. I am planning to display k value as an additional information into tooltip. Does anybody has any idea?

function createChart() {
    $("#chart")
        .kendoChart({
            xAxis: {},
            yAxis: {},
            seriesDefaults: {type: "scatterLine" },
            series: [{data: stats}],
            tooltip:{visible:true,template: "#= myTooltip(value) # "}
        });
}

function myTooltip(value) {
    return Math.abs(value.x) + ", "+Math.abs(value.y)+","+Math.abs(value.k);
}

Finally, here is the solution that I have come up so far. The key-point here is to access data via dataItem not via value-->(value.x, value.y) that restricts to access other elements in data objects other than only x and y.

It seems that value inherits from dataItem.

 tooltip:
     {
     visible:true,
     template: 
       "x : #=kendo.format('{0:n0}', (Math.abs(dataItem.x)))#, 
        y : #=kendo.format('{0:n0}', (Math.abs(dataItem.y)))#, 
        k : #=kendo.format('{0:n0}', (Math.abs(dataItem.k)))# "
     }
