Power BI - 矩阵计数空白行 [英] Power BI - Matrix Count Blank Rows

问题描述

我创建了一个矩阵，其中包含访问过的销售人员和他们的化学家的数据.

我添加了一个计数公式

客户计数 = DISTINCTCOUNTNOBLANK('源数据'[CustomerNameFull])

上面矩阵中的总数是拜访过化学家的推销员的总数，我想计算没有拜访过化学家的化学家总数.即空白的计数.空白计数应与总值一起显示.

任何帮助将不胜感激.

解决方案

有了预期的结果，我提出以下措施.为选定的推销员计算不同的未访问化学家:

未到访的化学家 :=VAR _customerCount = CALCULATE(DISTINCTCOUNTNOBLANK('源数据'[CustomerNameFull])，ALLSELECTED(日期))VAR _visitedCount = [客户数量]返回 _customerCount - _visitedCount

还有一个格式化矩阵:

未访问的客户数 =IF ( [客户数量] <> 空白 () ,转变 (真的 ()，NOT IINSCOPE ('源数据'[CustomerNameFull]) &&IINSCOPE ( 日期[月] ) ,[客户数] &"(& [未访问的化学家] & ")",格式([客户数量]，#")))

请注意，这里我使用的是日期表，而不是在 INVDATE 列上使用自动日期/时间.无论如何，这被认为是最佳实践.请记住设置正确的排序列，请参阅此处的指南:

结果如下:

I have created a matrix having data of salesman and their chemist visited.

I have added a count formula

Customer Count = DISTINCTCOUNTNOBLANK('Source Data'[CustomerNameFull])

The total in the above matrix is of the salesman who visited the chemist, along with that I want to calculate the total of chemist that is not visited by a salesman. i.e. the count of the blank. The blank count should be shown along with the total value.

Expected Output

Below is the expected output that I want. The zero total is the distinct count

Any help would be highly appreciated.

解决方案

With the expected result in place I propose the following measures. One to count the distinct unvisited chemists for the selected salesman/salesmen:

Unvisited Chemists := 
VAR _customerCount = CALCULATE ( DISTINCTCOUNTNOBLANK ( 'Source Data'[CustomerNameFull] ) , ALLSELECTED ( Dates ) )
VAR _visitedCount = [Customer Count]
RETURN _customerCount - _visitedCount

And one to format the matrix:

Customer Count w/ Unvisited = 
IF ( [Customer Count] <> BLANK () ,
    SWITCH ( 
        TRUE (), 
        NOT ISINSCOPE ( 'Source Data'[CustomerNameFull] ) && ISINSCOPE ( Dates[Month] )  ,
        [Customer Count] & " (" & [Unvisited Chemists] & ")" ,
        FORMAT ( [Customer Count] , "#" )
    )
)

Please note that here I am using a date table instead of using auto date/time on the INVDATE column. This is considered best practice anyway. Remember to set the correct sort column, see guide here: https://docs.microsoft.com/en-us/power-bi/create-reports/desktop-sort-by-column

I have used a simple date table:

Dates = 
ADDCOLUMNS ( 
    CALENDARAUTO () , 
    "Year" , YEAR ( [Date] ) ,
    "MonthNo" , MONTH ( [Date] ) ,
    "Month" , FORMAT ( [Date] , "MMMM" )
)

The data model looks like this:

The result looks like this:
