How do we calculate current day Vs Previous day in Domo.
@Salmas how do you expect this to behave?
Look at the inside
WHEN MAX(`Day`) = DAY(MAX(`Day`))-1 THEN...
that can NEVER be the same ... because MAX(DAY) can NEVER equal MAX(DAY) -1 .
Try putting your data into EXCEL and figure out how you'd construct the answer...
You could use a Period over Period Chart
For greater flexibility:
Here's how you can solve with LAG
Here's how you can solve with a Date DimensionJae Wilson

Hi, Agree to your point. And that was a mistake.
SUM(CASE WHEN (`Day`) = (MAX(`Day`))-1 THEN `Visits` END)
what about this statement?0
You're doing an aggregate of an aggregate (SUM OF MAX) which Domo doesn't like. I'd recommend going with a Date Dimension or LAG function as @jaeW_at_Onyx has outlined above.**Was this post helpful? Click Agree or Like below**

I dont think you can do it directly in the chart. You have to prepare your data in the ETL process in such a way you have the current day and prev day values in the same row.
Domo doesnt seem to have a function that would allow us to compare values directly in the chart. Maybe this could be a feature request.
I had to do this for a dashboard I was working on and after trying various things I changed my ETL where I joined my dataset with itself but joined on the previous day. In sql it'll be something like...
select <yourcolumnlist>, table1.value as current_day_value, table2.value as prev_day_value
from "a" as table1 join a as table2 on table1.date-1 = table2.date
Hope this helps.1
