Hi There –
We are evaluating the Metabase with Druid.
We were wondering if the tool would let us define an expression.
For example, is there a way to chart the percentage of successful transactions, where the percentage would be calculated on the fly with an expression –
For example, with a Druid visualization tool Pivot (https://github.com/implydata/pivot), we can define a “measure” as below and it would derive the % on the fly …
- name: percentage_unique_accts_successful
title: Percent Successful Accounts
expression: $main.filter($flag == ‘Approved’).countDistinct($acct_unique) / $main.countDistinct($acct_unique) * 100
Thanks for any help in advance.
