在我的nvd3 lineWithFocusChart中，y轴数据外观已连接起来。我有正确格式的json数据，但y轴数据仍未正确显示。我已将参考插头插入http://plnkr.co/edit/QwMbTL4co0wMVKaQurxq?p=preview。

我什至正确使用了刻度格式，但外观仍然不正确。如何使此图表正确显示y轴数据？

 tickFormat: function(d){
                        return  d3.time.format('%d/%m/%y')(
                                                new Date(d))
                    }

我在下面使用了排序功能。但是仍然无法正常工作。

angular.forEach($scope.data, function(series, index) {
                            series.values.sort(function(a, b) {
                                return a[0] - b[0];
                            });
                        });

我不确定Angular的工作方式。从NVD3的角度来看，它需要如下所示，并替换y为已排序的时间戳。尝试将排序的数据结构传递到图表中。

试试这个样本数据集结构：
