Qlik sense has the capability to create variables that can be used in the script, and also in the user interface.

As a developer, we can use the variables editor when editing a sheet, but we can change a variable when in view mode.

There will be questions such as the following:

• How to enable the user to choose how many customers to see in a bar chart?
• How to enable end users to input data in a variable to simulate some calculation scenarios?
