帆软 FineReport 绘制漏斗图

七一建党节，祝党生日快乐！
夏日炎炎，周末在家，想起在用帆软做页面展示的时候，使用到了漏斗图，记录下来，方便查看。
以订单销量变化为例，分为五个阶段，商品浏览人数，点击商品人数，创建订单人数，加入购物车人数和支付订单任务等，来实现效果。展示效果大致如下图所示。

第一步、构造基本列表

新建数据集，根据五个阶段来组装SQL，即通过union连接后再group by 实现统计，查询SQL如下所示，仅做参考，可根据具体业务调整。

select 
data_type,
sum(aa.pvNum) as pvNum,
sum(aa.clickNum) as clickNum,
sum(aa.createNum) as createNum,
sum(aa.cartNum) as cartNum,
sum(aa.payNum) as payNum
from (
SELECT 
        '商品浏览人数' AS 'data_type',
         COUNT(*) AS pvNum,
				0 AS clickNum,
        0 AS createNum,
        0 AS cartNum,
				0 AS payNum
    FROM
        tb_order
    WHERE
        1 = 1 
        AND DATE_FORMAT(created_time, '%Y-%m-%d') >= DATE_ADD('${beginDate}', INTERVAL 1 DAY)
        AND DATE_FORMAT(created_time, '%Y-%m-%d') <= DATE_ADD('${endDate}', INTERVAL 1 DAY)
	UNION ALL 
		SELECT 
        '点击商品人数' AS 'data_type',
				0 AS pvNum,
        COUNT(*) AS clickNum,
				0 AS createNum,
        0 AS cartNum,
				0 AS payNum
    FROM
			tb_order
    WHERE
        1 = 1 
		and order_status IN ('CO','OP','FN')
        AND DATE_FORMAT(created_time, '%Y-%m-%d') >= DATE_ADD('${beginDate}', INTERVAL 1 DAY)
        AND DATE_FORMAT(created_time, '%Y-%m-%d') <= DATE_ADD('${endDate}', INTERVAL 1 DAY)
	UNION ALL 
		SELECT 
        '创建订单人数' AS 'data_type',
				0 AS pvNum,
        0 AS clickNum,
        COUNT(*) AS createNum,
				0 AS cartNum,
				0 AS payNum
    FROM
         tb_order
    WHERE
        1 = 1 
	and order_status = 'CO'
	AND DATE_FORMAT(created_time, '%Y-%m-%d') >= DATE_ADD('${beginDate}', INTERVAL 1 DAY)
	AND DATE_FORMAT(created_time, '%Y-%m-%d') <= DATE_ADD('${endDate}', INTERVAL 1 DAY)
	UNION ALL 
	SELECT 
        '加入购物车人数' AS 'data_type',
				0 AS pvNum,
        0 AS clickNum,
        0 AS createNum,
        COUNT(*) AS cartNum,
				0 AS payNum
    FROM
         tb_order
    WHERE
        1 = 1 
	and order_status = 'CA'
	AND DATE_FORMAT(created_time, '%Y-%m-%d') >= DATE_ADD('${beginDate}', INTERVAL 1 DAY)
	AND DATE_FORMAT(created_time, '%Y-%m-%d') <= DATE_ADD('${endDate}', INTERVAL 1 DAY)
UNION ALL 
	SELECT 
        '支付订单人数' AS 'data_type',
				0 AS pvNum,
        0 AS clickNum,
        0 AS createNum,
        0 AS cartNum,
        COUNT(*) AS payNum
    FROM
         tb_order
    WHERE
        1 = 1 
	and order_status = 'OP'
	AND DATE_FORMAT(created_time, '%Y-%m-%d') >= DATE_ADD('${beginDate}', INTERVAL 1 DAY)
	AND DATE_FORMAT(created_time, '%Y-%m-%d') <= DATE_ADD('${endDate}', INTERVAL 1 DAY)
) aa

绘制列表，对应字段绑定，效果如下图所示。

在浏览器预览效果如下。

第二步、绘制漏斗图

在列表下方单元格，点击属性列表，选择插入元素-插入图表，在类型中选择漏斗图(新特性)，操作如下图所示。

构造数据源，类似的，五个阶段要分别拼接，展示值和对应的显示名要分开，即 key-values形式，注意要添加排序字段。

SELECT 
    data_type, num
FROM
    (SELECT 
        '商品浏览人数' AS 'data_type',
            COUNT(*) AS num,
            1 AS ordSeq
    FROM
        tb_order
    WHERE
        1 = 1 
        AND DATE_FORMAT(created_time, '%Y-%m-%d') >= DATE_ADD('${beginDate}', INTERVAL 1 DAY)
        AND DATE_FORMAT(created_time, '%Y-%m-%d') <= DATE_ADD('${endDate}', INTERVAL 1 DAY)
	UNION ALL 
		SELECT 
        '点击商品人数' AS 'data_type',
            COUNT(*) AS num,
            2 AS ordSeq
    FROM
			tb_order
    WHERE
        1 = 1 
        and order_status IN ('CO','OP','FN')
        AND DATE_FORMAT(created_time, '%Y-%m-%d') >= DATE_ADD('${beginDate}', INTERVAL 1 DAY)
        AND DATE_FORMAT(created_time, '%Y-%m-%d') <= DATE_ADD('${endDate}', INTERVAL 1 DAY)
	UNION ALL 
		SELECT 
        '创建订单人数' AS 'data_type',
            COUNT(*) AS num,
            3 AS ordSeq
    FROM
         tb_order
    WHERE
        1 = 1 
        and order_status = 'CO'
	AND DATE_FORMAT(created_time, '%Y-%m-%d') >= DATE_ADD('${beginDate}', INTERVAL 1 DAY)
	AND DATE_FORMAT(created_time, '%Y-%m-%d') <= DATE_ADD('${endDate}', INTERVAL 1 DAY)
	UNION ALL 
	SELECT 
        '加入购物车人数' AS 'data_type',
            COUNT(*) AS num,
            4 AS ordSeq
    FROM
         tb_order
    WHERE
        1 = 1 
      and order_status = 'CA'
	AND DATE_FORMAT(created_time, '%Y-%m-%d') >= DATE_ADD('${beginDate}', INTERVAL 1 DAY)
	AND DATE_FORMAT(created_time, '%Y-%m-%d') <= DATE_ADD('${endDate}', INTERVAL 1 DAY)
UNION ALL 
	SELECT 
        '支付订单人数' AS 'data_type',
            COUNT(*) AS num,
            5 AS ordSeq
    FROM
         tb_order
    WHERE
        1 = 1 
     and order_status = 'OP'
	AND DATE_FORMAT(created_time, '%Y-%m-%d') >= DATE_ADD('${beginDate}', INTERVAL 1 DAY)
	AND DATE_FORMAT(created_time, '%Y-%m-%d') <= DATE_ADD('${endDate}', INTERVAL 1 DAY)
    ) main
ORDER BY ordSeq asc
;

在编辑栏-数据，数据来源选择数据集数据，即上一步新建的，选择使用字段值，指定系列名和值，效果如下所示。

在编辑栏-样式，可设置漏斗图的标题，图例等信息，效果所下图所示。

放大图的范围，即选中区域后，合并单元格，如下图所示。

在图例页签下，勾选图例可见，在浏览器预览效果如下图所示。

比如可以使用标签，在编辑栏-格式，标签下-标签，使用标签。

在浏览器展示效果如下图所示。

以上就是漏斗图添加的过程，帆软自带有很多属性，可以调试查看效果，祝好！

异常处理

【1】结果显示乱码，如？？？？
处理方案：
在数据库连接后指定编码方式为 utf8

?useUnicode=true&characterEncoding=utf8
