It should be possible to use formula fields to group chart values.
E.g. I can create a formula that uses an IF statement, or a Date equation that returns days of the week in the formula, but then no way to produce charts grouped by these values, so if wanting to chart against:
- Derived Values (e.g. AM/PM, 1-3, 4-6, 7-9 etc)
Only work around I’ve found thus far is to have the derived value then set options on an option/radio button field, and then chart off of that field, but the table update rule to do this doesn’t fire until the record is subsequently updated (so I have to run a task each night to make an update to records where the option value is null) and makes the chart not update in real time.
