Bar Code Creator In .NET Framework Using Barcode creator for Reporting Service Control to generate, create bar code image in Reporting Service applications. The first formula fails as the Discontinued column is a TRUE/FALSE column The second formula produces the same result as the following formula: Barcode Recognizer In C# Using Barcode scanner for VS .NET Control to read, scan read, scan image in VS .NET applications.

Encoding EAN-13 In Java Using Barcode generation for Java Control to generate, create EAN-13 image in Java applications. This is yet another counting function COUNTBLANK(), as its name suggests, counts the blank values in a column This example is a calculated column in the Customers table Draw EAN / UCC - 13 In None Using Barcode encoder for Font Control to generate, create EAN13 image in Font applications. Painting Bar Code In Java Using Barcode encoder for BIRT Control to generate, create barcode image in Eclipse BIRT applications. Syntax
=COUNTBLANK(Customers[Region]) Result
Analysis
There are 60 customers that have a blank entry in the Region column Zeros are not blanks, and are not counted COUNTROWS() Here we have the last of the counting functions in this chapter These examples are calculated columns in the Employees table Syntax
=COUNTROWS(Orders) =COUNTX(RELATEDTABLE(Orders),Orders[EmployeeID]) =(Employees[CalculatedColumn2] / Employees[CalculatedColumn1]) * 100 C h a p te r 7 : Ag g re g a te Fu n c t i o n s
Result
Analysis
Davolio had nearly 15 percent of the orders COUNTROWS() tells you the total number of rows in the Orders table COUNTX() tells you the total number of rows in the Orders table in the row context of the current employee The second example could be replaced with =COUNTROWS(RELATEDTABLE(Orders)) However, COUNTX() is more flexible, as it lets you specify a specific column to count
MAX() MAX() returns the maximum value in a column This example is a calculated column in the Orders table
Syntax
=MAX(Orders[Freight]) Result
Prac tical PowerPivot & DAX Formulas for Excel 2010
Analysis
MAX() can handle numbers or dates For other data types, use MAXA() The result shows the largest freight charge for any order MAXX() The X-function version of MAX(), MAXX(), returns the maximum numeric or date value in a table column The column itself can be the result of an expression, as shown in this example There is no MAXAX() function This example is a calculated column in the Orders table Syntax
=MAXX(RELATEDTABLE('Order Details'), 'Order Details'[Quantity] * 'Order Details'[UnitPrice]) Result
Analysis
This example uses an expression for the second, column, parameter of MAXX() You could also reference either a regular or a calculated column here you might try the Sales Amount calculated column The result shows the maximum sales amount from the order lines for each order MAXA() MAXA() can cope with values that are neither numeric nor dates These examples are calculated columns in the Products table C h a p te r 7 : Ag g re g a te Fu n c t i o n s
Syntax
=MAX(Products[Discontinued]) =MAXA(Products[Discontinued]) Result
Analysis
The first example is for MAX() it causes an error The second example uses MAXA() and handles the TRUE/FALSE Discontinued column A value of TRUE counts as 1, while blanks, text, and FALSE count as zero MIN() MIN() works on numeric or date columns This example is a calculated column in the Orders table
Syntax
=MIN(Orders[Freight]) Result
Prac tical PowerPivot & DAX Formulas for Excel 2010
Analysis
The minimum freight charge for any order is only two cents (or two pence) The currency unit is determined by the regional settings in Control Panel and by the settings in the Formatting group of the PowerPivot Home ribbon MINX() MINX() is the X-function table version of MIN() This example is a calculated column in the Orders table Syntax
=MINX(RELATEDTABLE('Order Details'),'Order Details'[Quantity] * 'Order Details'[UnitPrice]) Result
Analysis
The formula returns the minimum sales amount of all the order lines belonging to a particular order
MINA() Here we have the A-function variation on the MIN() function These examples are calculated columns in the Products table Syntax
=MIN(Products[Discontinued]) =MINA(Products[Discontinued]) C h a p te r 7 : Ag g re g a te Fu n c t i o n s
Result
Analysis
The first example results in an error as the Discontinued column values are neither numeric nor dates In the second example, TRUE is counted as 1 and FALSE as zero MINA(), therefore, returns zero SUM() 1/2 This function, SUM(), and its related function SUMX(), are officially Math & Trig functions You can verify this in the Insert Function dialog However, they are also introduced in this chapter as they do perform an aggregation This example is a calculated column in the Order Details table Syntax
=SUM('Order Details'[Sales Amount]) Result
Prac tical PowerPivot & DAX Formulas for Excel 2010
Analysis
The formula is working out the total value of all sales in the Order Details table You might divide into the Sales Amount calculated column to ascertain the percentage contribution of each order line to overall sales SUM() 2/2 It probably bears reiterating that DAX functions and formulas can (in most cases) be used in either calculated columns or measures In the previous example, SUM() was a calculated column This example is a measure
