            },*/
            series: []
        }
    });
});

有两种情况我被卡住了。

当我尝试将图表导出为csv后，下钻文件名称应为“季度租金 - 资本趋势”，然后再向下钻取“年度租金 - 资本趋势”。例如向下钻取文件名之前应该像“Yearly rental-capital trend.csv” 向下钻取文件名后应该像“Quarterly rental-capital trend.csv”
导出到csv后，资本值应附加“K”。例如期间|租金价值|资本价值 2015年| 90 | 11.15 K

任何帮助都将受到赞赏，感谢并提前。
