谷歌饼图切片通过变量传递值为偏移量(google pie chart slices pass value through variable for offset)

 我正在使用谷歌图表api和angularjs.I需要通过变量设置切片值。所有示例我已经看到它们是硬编码或使用foreach循环。如何通过变量设置选定的饼图片值。这是我的代码？“selectedRow”变量作为字符串传递而不是作为变量传递。 
 
        $scope.onSelectRowFunction = function(selectedItem)
        { 

           var selectedRow = parseInt(selectedItem.row);
           $scope.chartpie.options = {
                "slices": {selectedRow : {"offset": 0.4}},
                "title": "Title is here",
                "isStacked": "true",                    
                "sliceVisibilityThreshold": 0,
                "displayExactValues": true
           };


       };

I am using google chart api and angularjs.I need to set slices value through variable.All example i have seen they are hardcoded or using foreach loop.How could i set selected pie slice value through variable.Here is my code?"selectedRow" variable is passing as a string not as a variable.
 
        $scope.onSelectRowFunction = function(selectedItem)
        { 

           var selectedRow = parseInt(selectedItem.row);
           $scope.chartpie.options = {
                "slices": {selectedRow : {"offset": 0.4}},
                "title": "Title is here",
                "isStacked": "true",                    
                "sliceVisibilityThreshold": 0,
                "displayExactValues": true
           };


       };
