    Want to know if we can get the color of the legend icon which is assigned to that part in the graph or chart.

    specially in pie charts.

    We haven’t set any color to the chart in data points. it is generating from the default color set.

    please help

    thank you

    manoj kumar,

    You can get the color of legend by using selectedColorset property of chart and index of dataPoint as shown in the code snippet below

    indexLabelFormatter: function (e) {
      var dpIndex = getDataPointIndex(e.dataSeries, e.dataPoint);
      var selectedColorSet = chart.get("selectedColorSet");
      var legendColor = e.dataPoint.legendMarkerColor ? e.dataPoint.legendMarkerColor : (e.dataPoint.color ? e.dataPoint.color : selectedColorSet[dpIndex % (selectedColorSet.length-1)]);
      console.log(legendColor);
    }
    .
    .
    .
    function getDataPointIndex(dataSeries, dataPoint) {
      return dataSeries.dataPoints.findIndex(dp => dp === dataPoint);
    }

    Also, please take at this updated JSFiddle for complete working code.
