DAX 根据度量列计数? [英] DAX to count based on a measure column?

问题描述

我在这里得到了很好的帮助:Power BI、DAX、多对一和关系表格

I was kindly helped here: Power BI, DAX, Many-to-one and relational tables

根据此数据生成度量列:

to produce a measure column based on this data:

Builds = 
DATATABLE(
    "Build", STRING,
    "App", STRING,
    {
        { "Build1", "App1" },
        { "Build1", "AppNotInApps1" },
        { "Build1", "App2" },
        { "Build1", "App9" },
        { "Build2", "App3" },
        { "Build2", "AppNotInApps2" },
        { "Build3", "App1" },
        { "Build3", "App5" },
        { "Build3", "App8" },
        { "Build3", "App9" },
        { "Build3", "AppNotInApps3" }
    }
)
 
Apps = 
DATATABLE(
    "App", STRING,
    "Status", STRING,
    {
        { "App1", "UAT" },
        { "App2", "Complete" },
        { "App9", "New" },
        { "App3", "Complete" },
        { "App5", "UAT" },
        { "App8", "Complete" }
    }
)

许多 Builds 都有一个应用程序，在 Builds.App = Apps.App 上加入.

Many Builds have one Apps, joined on Builds.App = Apps.App.

度量列(称为不完整")就是这个小美女:

The measure column (called 'incomplete') was this little beauty:

incomplete = 
IF(
    HASONEVALUE( Builds[Build] ),
    VAR CurrentBuild =
        SELECTEDVALUE( Builds[Build] )
    VAR CurrentApp =
        SELECTEDVALUE( Apps[App] )
    VAR Result =
        COUNTROWS(
            FILTER(
                ALLNOBLANKROW( Builds ),
                Builds[Build] = CurrentBuild
                    && RELATED( Apps[Status] ) <> "Complete"
                    && NOT ISBLANK( RELATED( Apps[Status] ) )
            )
        ) + 0
    RETURN
        IF( NOT ISBLANK( SELECTEDVALUE( Apps[Status] ) ), Result )
)

自从有了这个解决方案，我还加入了另一个名为 Sites 的表:

Since this solution, I have also joined another table called Sites:

Sites = 
DATATABLE(
    "Site", STRING,
    "Build", STRING,
    {
        { "Site1", "Build1" },
        { "Site2", "Build1" },
        { "Site2", "Build3" }
    }
)

连接在 Sites.Build = Builds.Build 上.而且您会注意到一个版本可以出现在多个站点中(不要问！).

The join is on Sites.Build = Builds.Build. And you'll notice that one build can appear in more than one site (don't ask!).

我在 Sites.Site 列上有一个切片器.

I have a slicer on the Sites.Site column.

这是一些示例数据:

Site.....Build.....App.....Status.....Incomplete
Site1....Build1....App1....UAT........2
Site1....Build1....App2....Complete...2
Site1....Build1....App9....New........2
Site2....Build1....App2....Complete...0
Site2....Build3....App1....UAT........3
Site2....Build3....App5....UAT........3
Site2....Build3....App8....Complete...1
Site2....Build3....App9....New........3

未完成"让我计算了有多少构建的状态不是完成"

The 'Incomplete' gives me a count of how many Builds have a status that is not 'Complete'

我现在想做的(这就是问题)是在我的 BI 视图中拥有三张卡片.

What i want to do now (and this is the question) is have three cards in my BI view.

卡片一(衡量标准?) - 计算不完整"计数为 0 的 Builds.Build 的 DISTINCT 数量.根据上面的数据，该值为 1.如果我在 Site1 上过滤，这将是 0.

Card one (a measure?) - Count the DISTINCT number of Builds.Build that has an 'incomplete' count of 0. Based on the data above, this value would be 1. If i filtered this on Site1, this would be 0.

卡片二(衡量标准?) - 计算不完整"计数不等于 0 的 Builds.Build 的 DISTINCT 数量.根据上述数据，该值将是2(两个不同的构建或 Build1 和 Build2).如果我在 Site2 上过滤这个，这将是 1 (Build3).

Card two (a measure?) - Count the DISTINCT number of Builds.Build that has an 'incomplete' count that is NOT equal to 0. Based on the data above, this value would be 2 (two distinct builds or Build1 and Build2). If i filtered this on Site2, this would be 1 (Build3).

卡三 - 卡一衡量标准(卡一衡量加上卡二衡量)的百分比

Card three - card one measure as a percentage of (card one measure plus card 2 measure)

我的页面上有过滤器(切片器)，所以我需要动态度量.

I have filters (slicers) on my page so i need the measure to be dynamic.

我已经为卡 1 尝试过这个，但它没有给我正确的值?

I've tried this for card 1, but it doesn't give me the correct value?

comp = CALCULATE(
DISTINCTCOUNT(Builds[Build]),
FILTER(ALLSELECTED(Build), [incomplete] = 0))

当然还有卡片 2:

comp = CALCULATE(
    DISTINCTCOUNT(Builds[Build]),
    FILTER(ALLSELECTED(Build), [incomplete] <> 0))

在我试用我的卡 3 之前，我有什么遗漏吗?

Is there something I'm missing before i try my card 3?

推荐答案

以下 DAX 有效:

COUNTROWS ( FILTER ( VALUES (Builds[build] ), Builds[Incomplete] = 0 ) )

我不完全确定为什么这不起作用:

I'm not entirely sure why this did NOT work:

COUNTROWS( DISTINCT( FILTER(Builds, Builds[Incomplete] = 0 ) ) )
