Managing variables in the script and layout

Qlik Sense provides the option to define variables in the script and in the user interface.

The variable editor interface enlists the existing variables created in the script, and provides the user with the option to create new variables as well.

Getting ready

For the purpose of this recipe, we will make use of an inline data load that gives the sales information for four countries:

1. Create a new Qlik Sense application, and call it QS_Variables.
2. Load the following script in the application:

Sales: 
LOAD * INLINE [ 
Country, Sales,COS 
USA, 1000,500 
UK, 2000,1000 
France, 3000,2500 
Germany, 4000,4700 
]; 
 
Let vTemporary = 'Sum(Sales)'; 
Let vRedColor=RGB (255, 0, 0); 
Let fSales= vTemporary; 
Let vTemporary = null(); 

How to do it…

1. Open the QS_Variables application.
2. Create a new sheet called Sales, and go to the Edit sheet mode for the sheet.
3. While in Edit sheet mode, notice that we have a new icon,
   
   , in the lower-left corner. Click on the icon to open...
