switch measures in chart through a button

[aheavy95]

Hi 

I am copying a project from qliksense to qlikview.

In sense, I added an Input button that when you pess it, the measure in a chart changes using the pick function (with a variable):

pick(vCustMeasure, count(distinct CustomerID), [Total orders],[Total income])

I'm trying to achieve the same in Qlikview. what is the best way to do it?

thanks

Alon
