如何从referesh $ on函数内部调用参数化方法？

Question

我有图div。在那个div我给了referesh工具，在客户端控制器中我必须传递参数函数，它将加载数据，然后将删除微调器

$scope.$on('panel-refresh', function(event, id) {
    spinnerId=id;
    // Instead of timeout you can request a chart data
    $scope.loadChart(streamStats, cloudStats);

});

这就是功能

function loadChart(streamStats, cloudStats)
{

    streamStats.forEach(function (day)
    {
        var date = new Date(day._id);
        date.setHours(0, 0);
        streamSeries.push([date, day.count]);
    });

    cloudStats.forEach(function (day)
    {
        cloudSeries.push([new Date(day._id), day.count]);
    });

    $scope.splineData = [
        {
            "label": "Data Streams",
            "color": "#564aa3",
            "data": streamSeries
        },
        {
            "label": "Cloud Syncs",
            "color": "#2f80e7",
            "data": cloudSeries
        }
    ];
    vm.splineData = $scope.splineData;
    $scope.$broadcast('removeSpinner', spinnerId);
}

现在问题是我收到此错误
