如何使Highcharts标记具有相对日期的日期时间X轴？

标签： javascript highcharts

我有以下图表显示多条曲线。这些曲线都发生在不同的时间，但是我将它们对齐，以便可以将它们视为同时发生。您可以通过将鼠标悬停在该点上来查看每个点的实际日期。

//set global chart options
$(document).ready(function() {
  Highcharts.setOptions({
    xAxis: {
      type: 'datetime',
    },

    yAxis: [{
      title: {
        text: 'FIXME',
        style: {
          color: '#4bb2c5',
        },
      },
      min: 0,
      maxPadding: 0,
    }, ],

    legend: {
      labelFormat: '<span style="font-size: xx-small;">{name}</span>',
    },

    tooltip: {
      formatter: function() {
        return Highcharts.dateFormat('%B %e, %Y', this.point.name) + "<br>Cases: " + this.point.y;
      }
    },
  });

  drawGraphMultipleCurves();
});

var plotMultipleCurves = null;

function drawGraphMultipleCurves() {
  //no need to redraw if we've already drawn the graph
  if (plotMultipleCurves != null)
    return;

  //shifted cumulative time series
  var cumulativeTimeSeriesMultipleCurves549 = [

现在的问题是X轴刻度/标签是空白的。允许Highcharts为X轴标签放置日期显然没有意义。我想放置相对日期，而不是放置绝对日期。基本上，我想要一种方法来确定最长时间序列的长度，并适当地缩放相对标签。以下是一些例子：

  • 在上面显示的图表中，有标签如“第1个月”，“第2个月”，“第3个月”等等。如果有太多标签/标记，那么它会跳过适当的金额（例如，“第1个月”，“第4个月”，“第7个月”）
  • 如果最长的时间序列缩短了很多（例如30天），则标签将是“第1天”，“第2天”等。同样，它会在适当时跳过标签/标记（例如，“第1天“，”第8天“，”第15天“。

如何在Highcharts中实现这一目标？

2 个答案:

答案 0 :(得分：1)

您可以使用xAxis.labels.formatter，例如：

＆＃13;
＆＃13; 
//set global chart options
$(document).ready(function() {
  Highcharts.setOptions({
    xAxis: {
      type: 'datetime',
    },

    yAxis: [{
      title: {
        text: 'FIXME',
        style: {
          color: '#4bb2c5',
        },
      },
      min: 0,
      maxPadding: 0,
    }, ],

    legend: {
      labelFormat: '<span style="font-size: xx-small;">{name}</span>',
    },

    tooltip: {
      formatter: function() {
        return Highcharts.dateFormat('%B %e, %Y', this.point.name) + "<br>Cases: " + this.point.y;
      }
    },
  });

答案 1 :(得分：0)

首先，Highcharts更喜欢以毫秒为单位的日期，即javascript内部表示，因此每当您在轴上使用日期时，都会以毫秒为单位给出日期。这是在Highcharts中使用日期的最快捷，最简单的方法，因为它通常可以很快找到标记轴的最佳方法。要将日期转换为毫秒，您可以使用以下内容：

var myDate = +new Date("some date")

如果您拥有该格式的日期，如果Highcharts没有准确地提供您想要的内容，请使用图表选项，如min，max，dateFormat等。
