Amal,

  Here is a fix for that:

        $scope.addSeries = function() {
          var named = [];
          var rnd = [];
          //Check if the series name exists and if it does exit this function
          //without adding the series
          for (var s = 0; s < $scope.highchartsNG.series.length; s++) {
            if($scope.item.name === $scope.highchartsNG.series[s].name){
              return;
            }
          }
          for (var i = 0; i < leng; i++) {
            switch ($scope.item.id) {
              case i:
                named[i] = $scope.item.name;
                rnd[i] = $scope.item.data;
                //named.disabled=true ;
                $scope.highchartsNG.series.push({
                  name: named[i],
                  data: rnd[i]
                })
                break;
            }
          }
        };‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Amal,

   The SmartMapping class chooses appropriate colors based on the number of classes and other variables like basemap used, etc. If you want to change those colors the you should not use the SmartMapping class and manually build your class break renderer.

Amal,

   I am not sure that I can help you as I do not use Angular or charting, but when I downloaded the rar it said it was an invalid rar when I tried to extract it.
