高图-负值的饼图

Question

Is there any way of avoiding this unusual behavior in Highcharts?

It happens when we update the chart with negative values on pie (donut) charts. Not on load.

Answer 1

In general, if you have negative values in the data that you are displaying, use a bar chart instead of a pie chart. Pie charts are supposed to represent a part of a total, a part-to-whole relationship, thus negative numbers won't work because you can't have a negative part of a total.

In case that you actually want to just show that value, try wrapping it in an absolute value;

 plotOptions: {
     pie: {
        allowPointSelect: true,
        cursor: 'pointer',
        dataLabels: {
           enabled: true,
           formatter: function() {
               return this.point.positive ? this.y : this.y * (-1);// <-- or wrap in absolute Math.abs(this.y)
           },
           color: 'black',
           style: {
              font: '13px Trebuchet MS, Verdana, sans-serif'
           }
        }
     }
  }

根据github线程，这应该在最新的master分支中解决。
