javascript - 无法在 Gauge Highchart 中设置目瞪口呆

Question

我已经尝试并走到了这一步，但仍然无法按照要求实现。

var chart = new Highcharts.chart('container', {

        chart:{
        type:'gauge',
        backgroundColor:'#000',
      },
      title: {
        text: null,
      },
      tooltip: {
        enabled: false
      },

      pane: {
        center: ['50%', '55%'],
        size: '250',
        startAngle: -135,
        endAngle: 135,
        background: {
          backgroundColor:'rgba(255, 255, 255, 0)',
          innerRadius: '60%',
          outerRadius: '100%',
          shape: 'arc',
          borderWidth: 1,
        },
      },
      plotOptions: {
        gauge: {
          dial: {
            radius: '92%',
            backgroundColor: '#fff',
            borderColor: '#fff',
            borderWidth: 0,
            baseWidth: 4,
            topWidth: 1,
            baseLength: '80%', // of radius
            rearLength: '-67%'
          },
          pivot: {
            radius: '0%',
            borderWidth: 0,
            borderColor: null,
            backgroundColor: 'rgba(255, 255, 255, 0)',
          }
        }
      },
      yAxis: [{

        plotOptions: {

          useHTML:true,
          verticalAlign:'middle',
          x:0,
          y:0,
          format: '<div style="text-align:center; color:#fff; font-family: gargi; font-weight: normal; line-height: 33px;"><span style="text-align: center;font-size:38px; font-family: gargi; font-weight: normal; display:block;">{y}</span><span style="text-align: center;font-size:14px; font-family: gargi; font-weight: normal;" >Social Good</span></div>',
        },

      }]
      });

请引用 fiddle 来完成我的开发。 fiddle并通过图像检查所需的仪表图表。

请问有人已经完成了这一步，请帮忙

您需要两个 y 轴，因为您需要两组刻度 - 一组带有延伸到整个圆弧的标签，另一组延伸到表盘。

第二个 y 轴应链接到第一个，您需要使用 axis.tickPositioner 手动设置刻度。 .

 {
  linkedTo: 0,
  offset: -15,
  lineWidth: 0,
  labels: {enabled: false},
  minorTickInterval: null,
  tickWidth: 1,
  tickLength: 35,
  tickColor: 'rgba(255, 255, 255, 0.3)',
  tickPositioner: function () {
    //generate ticks from 0 to 175
    var interval = 3;
    return Array.apply(null, Array(Math.round(175 / interval))).map((v, i) => i * interval);
  }
}

可以使用svg演示属性设置虚线stroke-dasharray应用于 .highcharts-pane 类。

.highcharts-pane {
  stroke-dasharray: 1, 3
}
