Hello,

I have a table with columns divided as a date histogram.

and I want to compute the change in the column 'Rejected txs' between my two divisions.

Can I do this?

Thanks in advance

You cannot make calculations between several tables.
In a computed column formula, you can only reference current table columns.
Sorry
