需要使用 css3 从气泡图绘制箭头线到另一个 div

Question

我需要使用 jquery/javascript html5、css3 制作某种动画。不确定是否可能。我用三个气泡图创建了三个 div。我需要从一个 div（从气泡到下一个 div）动态绘制箭头线。

而我的期望是需要动态绘制从一个气泡到另一个气泡的箭头线。

我正在使用 Highcharts.js 气泡图。

我的代码：

您可以只使用一个 Highcharts 图表来创建图表。每个部分可以是一个单独的x轴和y轴：

  yAxis: [{
    ...
  }, {
    ...
  }, {
    offset: 0,
    lineWidth: 1,
    height: '40%',
    top: '60%',
    left: '20%',
    width: '60%',
    title: null
  }],
  xAxis: [{
    ...
  }, {
    ...
  }, {
    offset: 0,
    width: '60%',
    left: '20%',
    height: '40%',
    top: '60%'
  }]

然后，在render事件中Highcharts.SVGRendererclass的帮助下，使用存储在图表中的值绘制所需的连接。

  chart: {
    type: 'bubble',
    events: {
      render: function() {
        const chart = this;
        const series = chart.series;
        const yAxis3 = chart.yAxis[2];
        const p1 = series[0].points[0];

        if (!p1.customLink) {
          // create the connection only at first render
          p1.customLink = chart.renderer.path().attr({
            ...
          }).add();
        }
        // update the connection dimensions on each render
        p1.customLink.attr({
          d: [
            ...
          ]
        });
      }
    }
  }
