Recently I have seen a code in the production that is

 if (!angular.isUndefined(newVal)) {
   if(!angular.isUndefined(newVal.min)){
     $scope.dataPoints.min = newVal.min;
   }
   if(!angular.isUndefined(newVal.max)){
     $scope.dataPoints.max = newVal.max;
   }
   if(!angular.isUndefined(newVal.yellowRangeMin)){
     $scope.dataPoints.yellowRangeMin = newVal.yellowRangeMin;
   }
   if(!angular.isUndefined(newVal.yellowRangeMax)){
     $scope.dataPoints.yellowRangeMax = newVal.yellowRangeMax;
   }
   if(!angular.isUndefined(newVal.redRangeMin)){
     $scope.dataPoints.redRangeMin = newVal.redRangeMin;
   }
   if(!angular.isUndefined(newVal.redRangeMax)){
     $scope.dataPoints.redRangeMax = newVal.redRangeMax;
   }
 }

It could be optimized through loop as

 if (!angular.isUndefined(newVal)) {
   var props = ['min','max','yellowRangeMin','yellowRangeMax','redRangeMin','redRangeMax'];
   _.each(props, function (prop) {
     if(!angular.isUndefined(newVal[prop])){
       $scope.dataPoints[prop] = newVal[prop];
     }
   });
 }
