Dollar-sign expansion using an expression

Load script

Load the following data as an inline load in the data load editor:

// Load string “=MinString(Measure)” into variable VSelectMeasure
Let vSelectMeasure = '=MinString(Measure)';
MyTable1: // Create table and load values for Dim and Sales
Load * inline [
Dim, Sales
A, 150
A, 200
B, 240
B, 230
C, 410
C, 330 ];                      
 
 
MyTable2: // Create table and load aggregations as field values for Measure
Load * Inline [
Measure
avg(Sales)
sum(Sales)
count(distinct Dim)];

For more information about using inline loads, see Using inline loads to load data.

Explanation

The script allows you to select a measure by referencing the measure in a chart expression. The chart expression contains the variable expansion $(=MinString(Measure)). MinString() finds string values in the expression and returns the first text value sorted alphabetically, in this case avg(Sales). This makes it possible to interactively decide (and select) which expression to use in a visualization without accessing and manipulating the properties of the object.

Output

Create the following table in Qlik Sense by using:

• Dimension: Dim

• Measures:

  • ='$(vSelectMeasure)'

  • =$(=MinString(Measure))

  • Avg(Sales)

Load script

Load the following data as an inline load in the data load editor:

Let vDivision = '=MinString(Numerator) / MinString(Denominator)';
Load recno() as Numerator autogenerate 100;
Load recno() as Denominator autogenerate 100;

Explanation

This script generates a pair of fields, containing 100 values each, that function as Numerators and Denominators in a calculation of the quota between the two. The chart measure contains the variable expansion ='$( vDivision )' , making it possible to interactively decide (and select) which quota to be calculated.

Output

Create the following table in Qlik Sense by using:

• Dimensions:

  • Numerator

  • Denominator

• Measure: ='$(vDivision)'

The resultant quota (Totals) is affected by the selected values in the fields. Numerator (=5) and Denominator (=3) and will be recalculated with each new selection in either field.
