I require a very simple implementation to be able to support this feature at the dashboard folder level.

solution A: On bar charts, Add a toggle for display label group count.

In the appended picture, I've set up a bar chart which uses Assignees ie: teams/vehicles on X axis and Task Number on Y axis. When I group Y axis by due date, the resulting groups define the amount of vehicle trips which were completed for that project. That total would be 12 while total number of tasks is 15. That is because the footing and layout teams completed multiple tasks on the same day...

I believe solution A to be ideal as the development time is minimal and it doesn't undermine any current system and could be toggled by any user.

solution B: give option to measure group number rather than task number in Y axis. The development time on this is so much steeper...

solution C: grant calculations the ability to result a group and subgroup combination. This is again much more lead time and might be supported in the future.

Regardless, solutions B and C can coexist with A in the long-term but solution is so much simpler.
