Add-ons and calculation Condition

[MoslemTeymoori]

Hello every one,

I would like to know the calculation Condition of a KPI or a chart in Add-ons part in the right panel of Qliksense is for only showing and hiding the object or for preventing the calculation of the dimensions and measures. because as its name says it MUST prevent the calculation in order to speed up the performance. but as I am trying to deal with it, for me it is just a show and hide condition because when I change the filter the calculation condition is false it calculates in the background and the performance of my app is the same as before.

any hints? 

Thank you so much 🙂

This is the idea of this field:
"Data handling: Calculation condition: Specify an expression in this text field to set a condition that needs to be fulfilled (true) for the object to be displayed. The value may be entered as a calculated formula. For example: count(distinct Team)<3. If the condition is not fulfilled, the message or expression entered in Displayed message is displayed.

A calculation condition is useful when a chart or table is very big and makes the visualization slow to respond. A calculation condition can then help so that for example an object does not show until the user has filtered the data to a more manageable level by applying selections."

Basically if you do not display the object the calculation won't happen.
As an example of good practice is having the first page of your app as a cover page so it does not have any calculation happening  when you open it.
