您可以根据生成的面包屑更新导出的字幕文本。例如：

   chart: {
     ...,
     events: {
       redraw() {
         const breadcrumbs = this.breadcrumbs;
         breadcrumbsText = '';

         if (breadcrumbs) {
           breadcrumbs.list.forEach(list => {
             if (breadcrumbsText) {
               breadcrumbsText += ' / '
             }
             breadcrumbsText += list.levelOptions.name;
           });
         }
       },
       load() {
         if (this.renderer.forExport) {
           this.setSubtitle({
             text: breadcrumbsText
           });
           Highcharts.drawTable(this);
         }
       }
     },
   }
