Highcharts - Treemap数据点限制

Question

我尝试通过调用REST API来加载超过1000个数据点。但是当数据点超过1000时，数据点将不会加载（显示白色图表）。我尝试使用turboThreshold但未成功。对此有何解决方案？以下是我的代码。

var data = {
          'TotalSales': {
                'Cat1': {
                    'Subcat1':{
                        'Prod1': '200',
                        'Prod2': '500',
                        'Prod3': '300'
                    },
                    'Subcat2':{
                      'Prod1': '400',
                      'Prod2': '100',
                      'Prod3': '600'
                    } 
                },
             'Cat2': {
                    'Subcat1':{
                      'Prod1': '200',
