Using Variables in Chart Expressions or Measures

[#1]

Hi All.

I am quite new to Qlik Sense and trying to calculate Sales from Last Quarter vs This Quarter

So I have a Purchase Amount and a Purchase Date.

I set the following in the load Statement

LET vThisQuarter = 'Q' & Ceil(Month(Today())/3);

LET vLastQuarter = 'Q' & Ceil(Month(Today())/3-1);

Now I am trying to create the formula that will give me Q1 and Q2 sales.  I am not sure what to do.  Any suggestions.

Thanks,

David

That is what I tried and it worked.  The problem is that hardcodes Q1 and Q2 into the formula.  I want to pass a variable so when the Q2 changes to Q3 I dont have to update the formula.

Does this make sense?

Thanks

Just use dollar sign expansion to replace the hard coded values with the variable content:

=sum({$<Quarter={'$(vLastQuarter)'}>}sales)

=sum({$<Quarter={'$(vThisQuarter)'}>}sales)
