Max - chart function

Max() finds the highest value of the aggregated data. By specifying a rank n, the nth highest value can be found.

Tip noteYou might also want to look at FirstSortedValue and RangeMax, which have similar functionality to the Max function.

Syntax:  

Max([{SetExpression}] [TOTAL [<fld {,fld}>]] expr [,rank])

Return data type: numeric

Arguments
Argument Description
expr The expression or field containing the data to be measured.
rank The default value of rank is 1, which corresponds to the highest value. By specifying rank as 2, the second highest value is returned. If rank is 3, the third highest value is returned, and so on.
SetExpression By default, the aggregation function will aggregate over the set of possible records defined by the selection. An alternative set of records can be defined by a set analysis expression.
TOTAL If the word TOTAL occurs before the function arguments, the calculation is made over all possible values given the current selections, and not just those that pertain to the current dimensional value, that is, it disregards the chart dimensions.

By using TOTAL [<fld {.fld}>], where the TOTAL qualifier is followed by a list of one or more field names as a subset of the chart dimension variables, you create a subset of the total possible values.

Defining the aggregation scope

Example: Chart expressions
Example Result
Max(UnitSales) Returns the highest value in the UnitSales field.
Max(UnitSales*UnitPrice) The value of an order is calculated by multiplying the number of units sold in (UnitSales) by the unit price. Returns the highest value of the result of calculating all possible values of (UnitSales) * (UnitPrice).
Max(UnitSales, 2) Returns the value for the second highest value.
Max(TOTAL UnitSales) The TOTAL qualifier means the highest possible value is found, disregarding the chart dimensions. For a chart with Customer as dimension, the TOTAL qualifier will ensure the maximum value across the full dataset is returned, instead of the maximum UnitSales for each customer.
Max({1} TOTAL UnitSales) The set analysis expression {1} defines the set of records to be evaluated as ALL, independent of any selection made. For example, if a specific customer is selected, it will still return the maximum UnitSales across the full dataset.
