选择并分组2x以获得图表

Question

我尝试按worker.id和month选择结果并将其分组。
我需要一张多普勒折线图，该月的工人销售额与今年的最佳月份相比

SELECT
   d02d5321.hart_orders.worker_id,

     sum(d02d5321.hart_orders.estimated_revenue) -
     sum(d02d5321.hart_orders.estimated_expenditure) as rvc 
FROM
    d02d5321.hart_orders
where YEAR(d02d5321.hart_orders.add_time) = YEAR(CURRENT_DATE())
group BY
    d02d5321.hart_orders.worker_id,MONTH(d02d5321.hart_orders.add_time)  order by rvc ASC;
