您可以根据点数调整图表的高度。下面是此功能的简单实现：

let spacePerPoint;
 let allowChartRedraw = true;

 Highcharts.chart('container', {
   chart: {
     type: 'bar',
     width: 600,
     height: 600,
     events: {
       load() {
         spacePerPoint = this.plotSizeX / this.series[0].points.length;

         if (this.renderer.forExport) {
           Highcharts.drawTable(this);
         }
       },
       redraw() {
         if (allowChartRedraw) {
           allowChartRedraw = false;

           this.setSize(
             null,
             this.chartHeight - this.plotSizeX + this.series[0].points.length * spacePerPoint
           );

           allowChartRedraw = true;
         }
       }
     }
   },
   ...
 });
