DAX MIN on Measure 结果为 0 而 table 中没有 0

Question

每个客户的展位 space 的详细数据来自 table [ExhibitorClass_Details]。措施 [Class_Booth_Space_ALL] class 通过展位 space 将客户确定为 A、B、C 或 D。
为了能够在视觉效果中使用此度量，我有一个 [Class] table 以及静态值 A、B、C 和 D。

我需要根据 Class.

找到 MAX、MIN、AVG... 展位 space 为了计算每个 classicication 的 MAX 展位 space，我创建了这个度量：

Visual Count Class MAX Booth Space ALL = 
  VAR _rank_class = SELECTEDVALUE('Class'[Class]) 
  return MAXX('ExhibitorClass_Details', if([Class_Booth_Space_ALL] = _rank_class,
               calculate(MAX(ExhibitorClass_Details[Booth_Space_ALLPREV])),0))

我的测量给出了 MAX 的正确结果。

但是 MIN 的错误结果：

Visual Count Class MIN Booth Space ALL = 
  VAR _rank_class = SELECTEDVALUE('Class'[Class]) 
  return MINX('ExhibitorClass_Details', if([Class_Booth_Space_ALL] = _rank_class,
               calculate(MAX(ExhibitorClass_Details[Booth_Space_ALLPREV])),0))

不是给我每个 class 的 MIN（如红色所示），而是结果为 0。

Visual Count Class MIN Booth Space ALL = 
  VAR _rank_class = SELECTEDVALUE('Class'[Class]) 
  return MINX('ExhibitorClass_Details', if([Class_Booth_Space_ALL] = _rank_class,
               calculate(MIN(ExhibitorClass_Details[Booth_Space_ALLPREV])),0))

我也试过第二个版本，但它给出了相同的 0 结果。谁能帮帮我。

这里是例子 [ExhibitorClass_Details] 数据：

|Costomer_Name|Booth_Space_ALLPREV|
|Megatech|30|
|CyberMunch|210|
|Digiwell|410|
|Innovix|110|
|Cloudmore|1410|
|Systemiq|610|
|Smartsoft|150|
|Clickwell|2410|
|Weblund|170|
|Quanterra|90|
|Avantex|270|
|Ventura|150|
|Sphere|450|
|Bitling|70|
|Elementaliq|130|

这里是截断点：

|A|2000|
|B|1000|
|C|500|
|D|0|

和class化的截止度量：

Class_Booth_Space_ALL = 
SWITCH(TRUE(),
    SUMX(ExhibitorClass_Details, ExhibitorClass_Details[Booth_Space_ALLPREV]) >= [Booth Space ALL A CutOff],"A",
    SUMX(ExhibitorClass_Details, ExhibitorClass_Details[Booth_Space_ALLPREV]) >= [Booth Space ALL B CutOff]
    && SUMX(ExhibitorClass_Details, ExhibitorClass_Details[Booth_Space_ALLPREV]) < [Booth Space ALL A CutOff],"B",
    SUMX(ExhibitorClass_Details, ExhibitorClass_Details[Booth_Space_ALLPREV]) >= [Booth Space ALL C CutOff]
    && SUMX(ExhibitorClass_Details, ExhibitorClass_Details[Booth_Space_ALLPREV]) < [Booth Space ALL B CutOff],"C",
    SUMX(ExhibitorClass_Details, ExhibitorClass_Details[Booth_Space_ALLPREV]) >= [Booth Space ALL D CutOff]
    && SUMX(ExhibitorClass_Details, ExhibitorClass_Details[Booth_Space_ALLPREV]) < [Booth Space ALL C CutOff],"D",
    "N/A")

Answer 1

不确定我是否完全理解您当前对 Visual Count Class MAX Booth Space ALL 和 Visual Count [=21] 的构造=] MIN 展位 Space ALL。除非我遗漏了什么，否则他们似乎不必要地同时使用 MIN 和 MINX.

我会使用类似的东西：

Visual Count Class MIN Booth Space ALL =
VAR _rank_class =
    SELECTEDVALUE( 'Class'[Class] )
RETURN
    CALCULATE(
        MIN( ExhibitorClass_Details[Booth_Space_ALLPREV] ),
        FILTER(
            ExhibitorClass_Details,
            [Class_Booth_Space_ALL] = _rank_class
        )
    )

Answer 2

尝试：

Visual Count Class MIN Booth Space ALL = 
VAR _rank_class = SELECTEDVALUE('Class'[Class]) 
return
CALCULATE(
  MIN( ExhibitorClass_Details[Booth_Space_ALLPREV] ),
  ALL( ExhibitorClass_Details ),
  ExhibitorClass_Details[Booth_Space_ALLPREV] = _rank_class,
  ExhibitorClass_Details[Booth_Space_ALLPREV] > 0
)

DAX MIN on Measure 结果为 0 而 table 中没有 0

DAX MIN on Measure results in 0 without 0 in table
