高图表活动仪表始终在中心显示文本

Question

我想使用Highchart的活动仪表作为某种围绕文本形式的数字/图形的圆形动画。默认行为是，仅当用户将鼠标悬停在序列上时，才会显示图表中心的文本。

穆斯塔法在这里有一个现有的解决方案：http://jsfiddle.net/mushigh/ubb2wz72/

但问题是，如果我删除 2 个默认系列中的 3 个（只剩 1 个），此解决方案将不再有效。这是我的小提琴：https://jsfiddle.net/v21zefzs/

控制台中有错误。您应该修复负责呈现箭头的代码。

   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': '#303030',
            'stroke-linecap': 'round',
            'stroke-linejoin': 'round',
            'stroke-width': 2,
            'zIndex': 10
        })
        .translate(190, 61)
        .add(this.series[0].group); //it tried add path to a non-existing 3rd series
