Highcharts - 如何使用 HTML 表中的多个系列制作散点图

Question

我正在尝试将 highcharts 图表与 HTML 表格链接，看来我可以将两者链接得很好，但是我无法找到有关如何为 散点图定义多个系列的任何文档或示例 - 我能找到的一切都是条形图或折线图，不能很好地转化为散点图。

我尝试过使用switchRowsAndColumns:true，但这会导致图表出错。我什至尝试过使用多列来添加系列，它工作到一半，但不允许我定义 x 值（它将行 # 作为 x，我输入的值作为 y），也不允许我定义其他系列的剩余字段（名称、用户、日期等）。

有什么建议吗？

Highcharts.setOptions({
    lang: {
        thousandsSep: "",
    }
});

Highcharts.chart('container', {
    data: {
        table: 'datatable',
        firstRowAsNames: false,
        startRow: 1,
        seriesMapping: [{

您可以在将图表选项传递给图表构造函数之前使用complete 回调函数 (http://api.highcharts.com/highcharts/data.complete) 修改图表选项。

在你的例子中可以看起来像这样：

complete: function(options) {
  // create the second series
  options.series.push({
    data: []
  });

  // move the data to the second series
  var d0 = options.series[0].data,
    d1 = options.series[1].data;

  d1.push(d0.pop(), d0.pop());

}
