简单筛选选函数
和下面的效果一样
IF ( ISBLANK ( Sales[Quantity] ), 1, Sales[Quantity] ) 用其检测是否为空
IFERROR ( SQRT ( Test[Omega] ), BLANK() ) 有错误用空值替代
IF ( Sales[Quantity] = 0, BLANK(), Sales[Sales Amount] / Sales[Quantity] ) 简单的条件判断语句
DIVIDE ( Sales[Sales Amount], Sales[Quantity] ) 安全除法,若被除数为0,则返回0
Sales[Gross Margin] = Sales[Sales Amount] - Sales[Total Product Cost] 直接相减 计算列
[Total Sales] := SUM ( Sales[Sales Amount] ) 度量值
SUMX ( Sales, Sales[Order Quantity] * Sales[Unit Price] ) 参数( 表,表达式)。
COUNTROWS ( Table ) = COUNTA ( Table[Column] ) + COUNTBLANK ( Table[Column] ) 非空+ 空等于总行数
DISTINCTCOUNT ( Table[Column] ) = COUNTROWS ( DISTINCT ( Table[Column] ) )
SUMX (
FILTER ( Sales, Sales[Unit Price] > 10 ),
Sales[Sales Amount]
) 计算上下文
Sales[List Amount] = Sales[Order Quantity] * Products[List Price] 两表建立关系
Sales[List Amount] = Sales[Order Quantity] * RELATED ( Products[List Price] ) 没有建立关系则有这个函数
Products[Number Orders] = COUNTROWS ( RELATEDTABLE ( Sales ) )
Products[List Amount] =
SUMX (
RELATEDTABLE ( Sales ),
Sales[Order Quantity] * Products[List Price]
) 好像是两表之间是多对一的关系的话就用RELATEDTABLE
Products[Price Ranking] =
COUNTROWS (
FILTER (
Products,
Products[List Price] > EARLIER ( Products[List Price] )
)
) EARLIER表示一个变动的参数,表示在当前的自己之前的数,语句意思是计算价格排名,计算在产品表里面产品的价格比自己高的数的个数,计算行多少就是有多少高出自己。
CALCULATE (表达式 条件,条件 ...)
[Sales2006] :=
CALCULATE (
SUM ( Sales[Sales Amount] ),
Order Date[Year] = 2006
)
增加筛选条件,更颗粒化的选择数据
[Sales2006] :=
CALCULATE (
SUM ( Sales[Sales Amount] ),
FILTER ( ALL ( Order Date[Year] ), Order Date[Year] = 2006 )
)
VALUES
返回唯一值,和distinct差不多
[Sales2006if Selected] :=
CALCULATE (
SUM ( Sales[Sales Amount] ),
FILTER ( VALUES ( Order Date[Year] ), Order Date[Year] = 2006 )
)
区别之处,是否计算空值
Num Of Products := COUNTROWS ( Products )
Num Of Categories := COUNTROWS ( DISTINCT ( Categories[Product Category Name] ) )
Num Of Categories Including Missing := COUNTROWS ( VALUES ( Categories[Product Category Name] ) )
简单时间智能函数
[Sales] := SUM( Sales[Sales Amount] )
[Sales MTD] := TOTALMTD ( [Sales], 'Date'[Date] ) 月累计至今的销售额
[Sales QTD] := TOTALQTD ( [Sales], 'Date'[Date] ) 季度累计
[Sales YTD] := TOTALYTD ( [Sales], 'Date'[Date] ) 年累计
也可以这样:
[Sales MTD] := CALCULATE ( [Sales], DATESMTD ( 'Date'[Date] ) )
[Sales QTD] := CALCULATE ( [Sales], DATESQTD ( 'Date'[Date] ) )
[Sales YTD] := CALCULATE ( [Sales], DATESYTD ( 'Date'[Date] ) )
但更灵活:计算上个周期的数值(周期自定)
[PY Sales] := CALCULATE ( [Sales], DATEADD ( 'Date'[Date], -1, YEAR ) )
[PQ Sales] := CALCULATE ( [Sales], DATEADD ( 'Date'[Date], -1, QUARTER ) )
[PM Sales] := CALCULATE ( [Sales], DATEADD ( 'Date'[Date], -1, MONTH ) )
[PY Sales] := CALCULATE( [Sales], SAMEPERIODLASTYEAR( 'Date'[Date] ) ) 依然性的
[PY Total Sales] := CALCULATE( [Sales], PARALLELPERIOD( 'Date'[Date], -1, YEAR ) ) 这个不是按自然年度划分的,是指过去12个月为一年,而非去年的现在同期月
[YTD Over Total PY]:= DIVIDE ( [Sales YTD], [PY Total Sales] ) ,年累计销售额占比过去12个月
[PY YTD Sales] :=
CALCULATE (
[Sales],
SAMEPERIODLASTYEAR ( DATESYTD ( 'Date'[Date] ) )
)
[PY YTD Sales] :=
CALCULATE(
[Sales],
DATESYTD ( SAMEPERIODLASTYEAR ( 'Date'[Date] ) )
)
有点复杂了,嵌套了好几个函数
[MAT Sales] :=
CALCULATE (
[Sales],
DATESBETWEEN (
'Date'[Date],
NEXTDAY ( SAMEPERIODLASTYEAR ( LASTDATE( 'Date'[Date] ) ) ),
LASTDATE ( 'Date'[Date] )
)
)
不太适合,搞不懂
Units Last Date := CALCULATE ( SUM ( Inventory[Units Balance] ), LASTDATE ( 'Date'[Date] )
Units Last Non Blank :=
CALCULATE (
SUM ( Inventory[Units Balance] ),
LASTNONBLANK (
'Date'[Date],
CALCULATE ( SUM ( Inventory[Units Balance] ) )
)
)
Sales Road650Red44 :=
CALCULATE (
SUM ( Sales[Sales Amount] ),
Products[Product Name] = "Road-650 Red, 44"
比较不同之处
Sales Only Road650Red44 :=
CALCULATE (
SUM ( Sales[Sales Amount] ),
Products[Product Name] = "Road-650 Red, 44",
ALL ( Products )
自定义的年累计
[YTD] :=
CALCULATE (
[Original Measure],
FILTER (
ALL ( 'Date' ),
'Date'[Year] = MAX ( 'Date'[Year] )
&& 'Date'[Date] <= MAX ( 'Date'[Date] )
)
)
有几个客户
Unique Customers :=
CALCULATE (
DISTINCTCOUNT ( Customers[Customer Code] ),
Sales
)
统计函数
移动平均模板
Moving Average X 7 Days :=
AVERAGEX (
DATESINPERIOD (
'Date'[Date],
LASTDATE ( 'Date'[Date] ),
-7,
DAY
),
[Total Amount]
)
更快速的方法
Moving Average 7 Days :=
CALCULATE (
IF (
COUNT ( 'Date'[Date] ) >= 7,
SUM ( Sales[Amount] ) / COUNT ( 'Date'[Date] )
),
FILTER (
ALL ( 'Date'[Date] ),
'Date'[Date] > ( MAX ( 'Date'[Date] ) - 7 )
&& 'Date'[Date] <= MAX ( 'Date'[Date] )
)
)
参数表
[Sales Amount] :=
IF (
HASONEVALUE ( Scale[Scale] ),
SUM ( Sales[Sales Amount] ) / VALUES ( Scale[Scale] ),
SUM ( Sales[Sales Amount] )
) HASONEVALUE 和VALUES合在一起使用,表示选中某一个值
Discounted Sales Amount :=
IF (
HASONEVALUE ( Discounts[Discount Value] ),
[Sales Amount] * ( 1 – VALUES ( Discounts[Discount Value] ) ),
IF (
NOT ( ISFILTERED ( Discounts[Discount] ) ),
[Sales Amount],
BLANK ()
)
)如果啥都没有选的话就用源值替代
Top Sales Amount :=
IF (
HASONEVALUE ( 'Top'[Top] ),
IF (
RANKX (
ALL ( Sales[Product] ),
[Sales Amount]
) <= VALUES ( 'Top'[Top] ),
[Sales Amount],
BLANK ()
)
) 带参数表的topN
计算过去12个月的销售额
[MAT Sales] :=
CALCULATE (
[Sales Amount],
DATESINPERIOD (
'Date'[Date],
LASTDATE ( 'Date'[Date] ),
-1,
YEAR
)
)
多选条件下的排名,带切片器的那种
[Rank by Brand C] :=
IF (
HASONEVALUE ( Product[Brand] ),
RANKX ( ALLSELECTED ( Product[Brand] ), [Sales Amount] )
)
