自定义分类字段

功能概述

自定义字段可以在不影响原数据的情况下通过对现有数据进行计算而得到一个新的数据字段。

分类字段是在数据集基础上对数据进行分组并标记,从而形成的新字段。

type=info

提示

只有在“详情”视图模式下,才可以添加自定义字段。

添加分类字段

注意

- 只有当字段的数据类型为数值时才可以添加分类字段。

- 新添加的 Sql 表达式字段无法添加分类字段。

系统支持两种分类字段类型,包括固定分组和自定义分组。

固定分组

根据用户输入的分组大小对数据进行分组,并以当前数据所在的区间作为新字段的内容。

在字段所在行单击image2018-6-7_17-12-31.png,选择” 添加分类字段 “即可进入分类字段配置对话框。

type=info

缓存数据集中支持添加度量值和计算列,详见添加度量值和计算列

进入配置对话框后,为新增字段添加字段名称。然后选择分组规则,并进行具体配置。

例1 设置订单金额的固定分组如下图所示:

勾选订单编号、订单金额为输出字段,单击页面上方的预览按钮,效果如下:

自定义分组

用户可以插入多个数据分割点,并为每个分组范围定义分组名称,最终以当前数据所属的分组名称作为新字段的内容。

例2 设置订单金额的自定义分组,为字段命名为“订单金额分组”。

image

在插入数据分割点处输入200并单击“ 插入 ”按钮。

然后同样再插入500,并为不同分组进行命名。如下图所示:

勾选订单编号、订单金额为输出字段,单击页面上方的预览按钮,效果如下:
