如何在 Power BI 中使用度量筛选折线图？

Question

我目前在 Power BI 中有一个名为 Fruit 的 table。

这是来自 Fruit 的示例数据：

Issue id	Label	Label 1	Label 2	Label 3	Label 4	Created	Resolved	Time Difference (MINS)
1000	Apples	Grapes	Bananas	Oranges	Strawberries	14/03/2021 11:38:23	11/02/2022	525632
1001	Oranges	Pears	Apples	Bananas	Strawberries	13/03/2021 12:34:34	18/03/2022 11:38:23	524324
1002	Pears	Dragon Fruit	Apples	Strawberries	Dragon Fruit	04/03/2021 18:31:11	12/03/2022 11:38:23	525345
1003	Bananas	Oranges	Apples	Grapes	Pears	11/03/2021 19:34:57	11/03/2022 11:38:23	528264
1004	Grapes	Apples	Bananas	Pears	Strawberries	12/03/2021 12:32:52	15/03/2022 11:38:23	521927

我创建了一个 table 来将标签值合并为一个： AllLabel = SUMMARIZE(UNION(VALUES(Fruit[Label 1]), VALUES(Fruit[Label 2]), VALUES(Fruit[Label 3]), VALUES(Fruit[Label 4])),Fruit[Label 1])

我还创建了一个对标签进行计数并对其进行唯一过滤的度量： Apples Oranges Pears Bananas Strawberries Dragon Fruit Grapes:

SELECTEDFruit = 
var _selectedFruit = SELECTEDVALUE(AllLabel[Label 1])
return
CALCULATE(COUNTROWS(Fruit) , FILTER(Fruit,Fruit[Label 1] = _selectedFruit || Fruit[Label 2] = _selectedFruit || Fruit[Label 3] = _selectedFruit || Fruit[Label 4] = _selectedFruit))

这是 table 的样子：

我有一个折线图来计算平均解决时间：

但是，当我使用切片器选择特定水果时，它不会改变平均分辨率时间线图的值。

如何使用标签 1 切片器过滤平均分辨率折线图？

Answer 1

原因是你们的table没有关系。确保 table 之间存在关系。它可以是两个 table 之间的一个活动关系，您应该使用 dax 关系函数，例如 USERELATIONSHIP 公式来计算其他列之间的关系。但是我建议使用 pivot、unpivot 和 union dax 函数来创建另一个 table 以从切片器获得最佳结果，并且不需要您的 dax 公式 AllLabel

UnpivotedTable= FILTER(
UNION(
SELECTCOLUMNS('Fruit',"Created",[Created],"Resolved",[Resolved],"Time Difference (MINS)",[Time Difference (MINS)],"label",[Label]),
SELECTCOLUMNS('Fruit',"Created",[Created],"Resolved",[Resolved],"Time Difference (MINS)",[Time Difference (MINS)],"label",[Label 1]),
SELECTCOLUMNS('Fruit',"Created",[Created],"Resolved",[Resolved],"Time Difference (MINS)",[Time Difference (MINS)],"label",[Label 2]),
SELECTCOLUMNS('Fruit',"Created",[Created],"Resolved",[Resolved],"Time Difference (MINS)",[Time Difference (MINS)],"label",[Label 3]),
SELECTCOLUMNS('Fruit',"Created",[Created],"Resolved",[Resolved],"Time Difference (MINS)",[Time Difference (MINS)],"label",[Label 4])),[Label]<>"")
