高图-2个同步活动量表

时间：2018-10-09 13:30:53

标签： javascript highcharts

我从这个Highcharts activity gauge开始，尝试使其中两个水平对齐（类似于this other example）并同步。

基于第二个示例，我开始从第一个示例中修改代码，但到目前为止，我没有成功，第二个图表甚至都无法成功显示。

我做错了什么？

我的代码，也在JSFiddle中：

function renderIcons() {

  // Move icon
  if (!this.series[0].icon) {
    this.series[0].icon = this.renderer.path(['M', -8, 0, 'L', 8, 0, 'M', 0, -8, 'L', 8, 0, 0, 8])
      .attr({
        'stroke': '#303030',
        'stroke-linecap': 'round',
        'stroke-linejoin': 'round',
        'stroke-width': 2,
        'zIndex': 10
      })
      .add(this.series[2].group);
  }
  this.series[0].icon.translate(
    this.chartWidth / 2 - 10,
    this.plotHeight / 2 - this.series[0].points[0].shapeArgs.innerR -
    (this.series[0].points[0].shapeArgs.r - this.series[0].points[0].shapeArgs.innerR) / 2
  );

  // Exercise icon
  if (!this.series[1].icon) {
    this.series[1].icon = this.renderer.path(
        ['M', -8, 0, 'L', 8, 0, 'M', 0, -8, 'L', 8, 0, 0, 8,
          'M', 8, -8, 'L', 16, 0, 8, 8
        ]
      )
      .attr({
        'stroke': '#ffffff',
        'stroke-linecap': 'round',
        'stroke-linejoin': 'round',
        'stroke-width': 2,
        'zIndex': 10
      })
      .add(this.series[2].group);
  }
  this.series[1].icon.translate(
    this.chartWidth / 2 - 10,
    this.plotHeight / 2 - this.series[1].points[0].shapeArgs.innerR -
    (this.series[1].points[0].shapeArgs.r - this.series[1].points[0].shapeArgs.innerR) / 2
  );

  // Stand icon
  if (!this.series[2].icon) {
    this.series[2].icon = this.renderer.path(['M', 0, 8, 'L', 0, -8, 'M', -8, 0, 'L', 0, -8, 8, 0])
      .attr({
        'stroke': '#303030',
        'stroke-linecap': 'round',
        'stroke-linejoin': 'round',
        'stroke-width': 2,
        'zIndex': 10
      })
      .add(this.series[2].group);
  }

  this.series[2].icon.translate(
    this.chartWidth / 2 - 10,
    this.plotHeight / 2 - this.series[2].points[0].shapeArgs.innerR -
    (this.series[2].points[0].shapeArgs.r - this.series[2].points[0].shapeArgs.innerR) / 2
  );
}

示例中的问题是您没有单独的图表，而一个图表带有两个yAxis。在此处查看Highcharts同步图表示例：jsfiddle。请注意，每个图表都是单独的，并插入到单独的div容器中。

因此，首先创建两个实体表类型图表，然后将它们水平对齐。然后在包含图表的容器div元素上添加mousemove触发器。高图会包装所有浏览器事件，当您将鼠标悬停在图表系列上时，就会获得有关悬停的图表，系列等的信息。

使用悬浮序列索引在两个图表中的适当序列上调用onMouseOver()方法，并使用悬浮序列中的点刷新工具提示：

HTML：

<div id="container">
  <div id="container1"></div>
  <div id="container2"></div>
</div>

JS：

['mousemove', 'touchmove', 'touchstart'].forEach(function(eventType) {
  document.getElementById('container').addEventListener(
    eventType,
    function(e) {
      var chart,
        point,
        i,
        seriesIndex,
        event;

      for (i = 0; i < Highcharts.charts.length; i = i + 1) {
        chart = Highcharts.charts[i];
        event = chart.pointer.normalize(e);

        if (event.srcElement.point) {
          seriesIndex = event.srcElement.point.series.index;
        }

        if (chart.series[seriesIndex]) {
            point = chart.series[seriesIndex].points[0];
            chart.series[seriesIndex].onMouseOver();
            chart.tooltip.refresh(point);
        }

      }
    }
  );
});

注意，Highcharts.charts包含所有图表参考。
