PowerBI:切片器仅在选择超过1个值时才能过滤表

问题描述

我有一个表格，其中包含 5 个类别和单位，显示为 2 种类型，即实际和预算.

I have a table with 5 categories and units displayed into 2 types, Actual and budget.

我想过滤这个表.仅当在切片器中选择了 2 个或更多值时.像这样的东西.

I want to filter this table. Only when 2 or more values are selected in the slicer. Something like this.

我想添加一个度量，但不知道如何准确地使用 if 语句.

I though of adding a measure, but dont know how to work the if statement exactly.

Measure = IF(COUNTROWS(ALLSELECTED(Report[Shipment Group])) = 1, "Something which would not filter the units", SELECTEDVALUE(Report[Units], SUM(Report[Units])))

不确定这是否是正确的方法.想知道是否有任何其他方法是可能的.任何帮助都会有所帮助.提前谢谢你.

Not sure if this is correct approach.Would like to know if any other approach is possible. Any help would be helpful. Thank you in advance.

推荐答案

这是一个有点奇怪的要求，但我认为我有一些可行的方法.

This is a bit of an odd request, but I think I have something that works.

1. 首先，您需要为切片器值创建一个单独的表(否则您无法控制自己想要的过滤方式).您可以点击新建表格按钮并将其定义如下:

Groups = VALUES(Report[Shipment Group])

1. 将您的切片器设置为使用 Groups[Shipment Group] 而不是 Report[Shipment Group].

如下定义您的新度量:

Measure = IF(COUNTROWS(ALLSELECTED(Groups[Shipment Group])) = 1,
             SUM(Report[Units]),
             SUMX(FILTER(Report,
                         Report[Shipment Group] IN VALUES(Groups[Shipment Group])),
                  Report[Units]))

或等价的

Measure = IF(COUNTROWS(ALLSELECTED(Groups[Shipment Group])) = 1,
             SUM(Report[Units]),
             CALCULATE(SUM(Report[Units]),
                       FILTER(Report,
                              Report[Shipment Group] IN VALUES(Groups[Shipment Group]))))

注意:仔细检查 Power BI 是否未在 Groups 和 Report 表之间自动创建关系.你不想这样.

Note: Double check that Power BI has not automatically created a relationship between the Groups and Report tables. You don't want that.
