是否可以更改图形的粒度？我有这样的时间表：

如何更改粒度？该数据不会显示在几天而是几个月。例如：9月，10月，12月等。

Answer 1

将您的查询更改为月份的group和count数据

示例（mysql语法）

SELECT DATE_FORMAT(SHIPPEDDATE,'%y %M') as LABEL, COUNT(ORDERID) AS CNT_ORDERID 
FROM Orders 
GROUP BY YEAR(SHIPPEDDATE), MONTH(SHIPPEDDATE)
ORDER BY SHIPPEDDATE

注意：这会更改Dataset1中的字段（仅2，LABEL和CNT_ORDERID）和bucketExpression，valueExpression将指向新字段

如何更改highcharts中的粒度？
