Angular JS: Use different instances of scope

How can we use two different instances of scope objects

For example :

$scope.seriesdata = [
        [65, 59, 80, 81, 56, 55, 40],
        [28, 48, 40, 19, 86, 27, 90]
      ];
$scope.currentseries =  $scope.seriesdata;

Now if I update $scope.currentseries , $scope.series got automatically updated.

For Example : 

$scope.currentseriesdata.splice(index,1);

This updates both $scope.currentseriesdata and $scope.seriesdata

Before writing this : I read this

I dont need to work in factory .

I just need to know how to have different instances within controller

It's because you're assigning to currentseries reference to the array that is already referenced by seriesdata. This means you have two variables that point to one array.

You want to use slice

$scope.currentseries =  $scope.seriesdata.slice();

Just copy the contents before operating on them:

$scope.currentseries = angular.copy($scope.seriesdata);
