我尝试在折线图中显示API的数据,其中x轴为“date”值,y轴为“announces”值。我收到Highcharts错误#12,数据未显示在图表中。我将www.example.com属性结构化series.data为:[[date, announces],[date, announces], ...] .下面是我的代码:

dataChart: SequenceChartData[] = [];
bucketAnnouncements: Array<[Date, number]> = [];

ngOnInit(): void {
    this.chartService.getSequenceChartData(this.data.peerAS, this.data.peerIPAddress, this.data.prefix)
    .subscribe((data: SequenceChartData[]) => {
      this.dataChart = data;
      this.update = true;
      this.show = true;
      let firstDay = Infinity;
      let lastDay = -Infinity;
      for (const val of this.dataChart){
        const date = moment.utc(val.date).unix();
        if (firstDay > date) {
          firstDay = date;
        }
        if (lastDay < date) {
          lastDay = date;
        }
      }
      for (let n = firstDay; n <= lastDay; n += 300) {
        this.bucketAnnouncements[n] = [
          new Date(n * 1000),
          0
        ];
      }
      for (const val of this.dataChart) {
        const date = val.date;
        this.bucketAnnouncements[moment.utc(date).unix()][1] = val.announces;
      }

      this.chartOptions.series = [
          {
            name: 'ao',
            type: 'line',
            data: this.bucketAnnouncements,
            color: '#009879',
          }
        ];
        });
    }

使用console.log时,似乎数据分配正确:

1546300800: (2) [Tue Jan 01 2019 01:00:00 GMT+0100 (Central European Standard Time), 31]
1546301100: (2) [Tue Jan 01 2019 01:05:00 GMT+0100 (Central European Standard Time), 30]
1546301400: (2) [Tue Jan 01 2019 01:10:00 GMT+0100 (Central European Standard Time), 30]
1546301700: (2) [Tue Jan 01 2019 01:15:00 GMT+0100 (Central European Standard Time), 30]
1546302000: (2) [Tue Jan 01 2019 01:20:00 GMT+0100 (Central European Standard Time), 30]
1546302300: (2) [Tue Jan 01 2019 01:25:00 GMT+0100 (Central European Standard Time), 30]
1546302600: (2) [Tue Jan 01 2019 01:30:00 GMT+0100 (Central European Standard Time), 30]
...

我还按照错误提示将turboTreshold设置为更高的数字,但它仍然不起作用(仍然给出警告):

plotOptions: {
    series: {
        turboThreshold: 500000,
        ...
    }
}

为了更完整地理解我的代码,这里有一个github repository(无法解决合并冲突)

请注意date
例如,Tue Jan 01 2019 01:00:00 GMT+0100 (Central European Standard Time))不是Highcharts的数字,它只是一个字符串。
为了解决这个问题,请使用毫秒格式的时间戳。
在那里你可能会发现一些方法来转换它从一种格式到另一种。

将turboThreshold设置为0(零)。它将工作
