Question

我有这样的数据：

var data = [{
    x: Date.UTC(1951, 5, 22),
    name: 'First dogs in space',
    label: 'fds',
    dataLabels: {
        allowOverlap: false,
        format: '<span style="color:{point.color}">● </span><span style="font-weight: bold;" > ' +
            '</span><br/>{point.label}'
    },
}, {
    x: Date.UTC(1957, 9, 4),
    name: 'First artificial satellite',
    label: 'First artificial satellite',
}, {
    x: Date.UTC(1959, 0, 4),
    name: 'First artificial satellite to reach the Moon',
    label: 'First artificial satellite to reach the Moon',
}, {
    x: Date.UTC(1961, 3, 12),
    name: 'First human spaceflight',
    label: 'First human spaceflight',
}, {
    x: Date.UTC(1966, 1, 3),
    name: 'First soft landing on the Moon',
    label: 'First soft landing on the Moon',
}, {
    x: Date.UTC(1969, 6, 20),
    name: 'First human on the Moon',
    label: 'First human on the Moon',
}, {
    x: Date.UTC(1971, 3, 19),
    name: 'First space station',
    label: 'First space station',
}, {
    x: Date.UTC(1971, 11, 2),
    name: 'First soft Mars landing',
    label: 'First soft Mars landing',
}, {
    x: Date.UTC(1976, 3, 17),
    name: 'Closest flyby of the Sun',
    label: 'Closest flyby of the Sun',
}, {
    x: Date.UTC(1978, 11, 4),
    name: 'First orbital exploration of Venus',
    label: 'First orbital exploration of Venus',
}, {
    x: Date.UTC(1986, 1, 19),
    name: 'First inhabited space station',
    label: 'First inhabited space station',
}, {
    x: Date.UTC(1989, 7, 8),
    name: 'First astrometric satellite',
    label: 'First astrometric satellite',
}, {
    x: Date.UTC(1998, 10, 20),
    name: 'First multinational space station',
    label: 'First multinational space station',
}];

我想要当用户在任何标签上选择该标签被突出显示并使其所有其他颜色消失时。同样，当我将光标移到褪色的标签上时，它正在更改标签颜色，以便用户可以单击该标签。

您可以使用Custom-Events插件：https://www.highcharts.com/products/plugin-registry/single/15/Custom-Events来实现。

代码：

series: [{
  dataLabels: {
    events: {
      mouseover: function() {
        if (!this.dataLabel.isSelected) {
          this.dataLabel.attr({
            fill: '#efefef'
          });
        }
      },
      mouseout: function() {
        if (!this.dataLabel.isSelected) {
          this.dataLabel.attr({
            fill: '#fff'
          });
        }
      },
      click: function() {
        var point = this.point,
          series = point.series;

        series.points.forEach(function(p) {
          p.dataLabel.attr({
            fill: '#fff'
          });

          p.dataLabel.isSelected = false;
        });

        this.dataLabel.attr({
          fill: 'red'
        });

        this.dataLabel.isSelected = true;
      }
    }
  },
  marker: {
    symbol: 'circle'
  },
  data: data,
}]

如果未选中标签，如何在Highchart时间轴中使标签褪色？
