Get previous dates sum

Hello fellow QlikViewers!
I am trying to get the sum for the previous date in a chart, but it's not working. You can see the result in the attachement.
In the example one can see a date field together with the number of orders that specific date. Then I want to output the number of orders the day before. As you can see, that column does not work... It should look like the one after, called "Goal". That one is using the above() function, but since I will use this value in an aggregated expression later on, that solution doesn't work. The expression behind my failed column looks like this:
sum({<[Order Date] = {"$(=date(max([Order Date])-1))"}>} [Order Count])
Can someone please help me?
Thank you,
Stefan

Re: Get previous dates sum

I got it to work by creating a separate table "previous date", where the key was based on the date. But in the key value in the "previous date" table, the date was added one day. This way, the value in the previous table would be linked to another date in the normal table. And with that, I can access the number for the previous day while still using a regular calendar. I guess not all solutions can be made in the expressions alone

Get previous dates sum

Stefan,

You can use above() function:
above(sum([Order Count]))

Re: Get previous dates sum

No, unfortunately not. In the end I won't even have a column for the number of orders, they are just used in an expression. I have to aggregate over each date and calculate stuff, but in the end they will be applied for week/month dimensions. So even if I apply the above function here, when I switch the dimension to Month instead it won't work.

Get previous dates sum

Hi Stefan,

as far as i know you cant use a set analysis within the "row context", because it is evaluated just once per chart. Depending on what you want to achieve in the end you probably have to find a workaround (removing date dimension to work with sets, above() + rangesum functions/combos, 2 charts side by side etc)

greets,

Alright, bummer. Maybe I'll have to fix it in the data layer, creating a field for previous dates orders.Thanks for the clarification.
