javascript - Highcharts 6 时间线图

Question

(Highcharts 版本 6)

除了像本例这样的数据点之外，是否可以有一个时间线图表:

<script src="https://code.highcharts.com/stock/highstock.js"></script>

但不使用 highstock 而只使用 highcharts ？

我知道可以使用 xrange 模块，但它不完全相同:

如果范围足够长来模拟一条线，那么您就无法在线上添加“数据点”，并且如果您将范围设置得足够小以看起来像数据点，那么您就没有线。

注意我知道版本 7 中的新图表类型“时间线”，但我需要使用版本 6.1

是的，这是可能的。但是，您不能使用 flags 系列，因为它仅受 Highstock 支持。检查下面发布的演示和代码。

代码:

function toMs(yeah, month) {
  return Date.UTC(yeah, month, 1);
}

var series = [{
    // First series
    name: 'Running',
    color: 'green',
    id: 'green',
    dataRaw: [{
      y: 1,
      xRanges: [
        // first value: from; second value: to
        [toMs(2000, 1), toMs(2002, 8)],
        [toMs(2006, 10), toMs(2006, 11)]
      ]
    }]
  }, {
    // Second series
    name: 'Filed',
    color: 'yellow',
    id: 'yellow',
    dataRaw: [{
      y: 1,
      xRanges: [
        // first value: from; second value: to
        [toMs(2002, 8), toMs(2006, 10)]
      ]
    }]
  },
  {
    // Second series
    name: 'Granted',
    color: 'blue',
    id: 'blue',
    dataRaw: [{
      y: 1,
      xRanges: [
        // first value: from; second value: to
        [toMs(2006, 11), toMs(2021, 8)]
      ]
    }]
  }

].map(function(series) {
  series.data = [];
  series.dataRaw.forEach(function(dataRaw) {
    dataRaw.xRanges.forEach(function(xRange) {
      series.data.push([xRange[0], dataRaw.y], [xRange[1], dataRaw.y], [xRange[1], null]); // null breakes the line
    }); // forEach
  }); // forEach
  return series;
});

console.log(series);
