nvd3烛台图表不显示自定义数据

我有一个nvd3角度烛台图表,显示硬编码的数据刚刚好。但是当我把它指向另一个数据源(socket.io)时,它就不再显示了。

 $scope.getdata = function () {
    console.log("getting data!");
    io.socket.get('/feed/getpolodata', function (data, jwr, err) {
        var values = [];
        angular.forEach(data.candleInfo, function (r) {
            //$scope.data
            values.push({

                "date": r.date,
                "close": r.close,
                "open": r.open,
                "high": r.high,
                "low": r.low,
                "volume": r.volume,
                "adjusted": r.low

            });

            if (err) {
                console.log("Error getting data")
            }
        });

        $scope.data.push({values});

        console.log("js" + JSON.stringify($scope.data));
        console.log("js2" + JSON.stringify($scope.data2));
    })
};

$范围。数据包含自定义数据和$scope。数据包含用于测试的硬编码数据。

数据2:

    $scope.data2 = [{
    values: [
        { "date": 1499031328, "close": 0.00008231, "open": 0.0000816, "high": 0.00008267, "low": 0.0000816, "volume": 12.09695909596307, "adjusted": 0.0000816 },
        { "date": 1499031388, "close": 0.00008303, "open": 0.000083, "high": 0.0000837, "low": 0.00008294, "volume": 10.91308942290992, "adjusted": 0.00008294 }
    ]
}]

当我将图形的数据值指向data2时,它工作得很好。但是,当我指向$scope.data时,什么也不显示。

编辑:这是console.log的结果
