I would like to be able to use Time Tracked as a filter in Custom Pie charts and Bar Charts in Dashboards and Overviews, so I can see a pie chart of time tracked against certain Custom Fields.

This would be very useful!

I'm going to merge your request into an existing one for having more filter options for tracked time.

Yes, please please add this feature! By not having a more robust option for running reports or synthesizing data, we may need to go back to using Clockify and I absolutely don't want to use two separate systems, even if there is an add-on app.

Please implement this, this would be very helpfull to display data in graphs or pie charts or ...

This would be extremely helpful, especially for dashboards and tables.

Time tracked by date, user, list, etc would be incredibly useful.

this is definitely needed and a pretty standard feature in time reporting software. To go in more detail/further, there are select dashboard cards that can filter by time, but don't allow for robust reporting of some/all of time estimate, tracked, capacity, or nor offer sums/averages/% of combining these fields in any way

time tracking and time reporting cards filter by timeframe and one of them allows grouping by different aspects (space, folder, list, user), but won't show a totals calculation

timeline chart filters by timeframe on Xaxis, but doesn't offer time tracked on Yaxis (only time estimate)

calculation cards (numbers) don't have filtering by timeframe

the new timesheets page doesn't calculate totals for either time tracked or time capacity

none of these cards offer a way to calculate time tracked/time estimated

none of these cards offer time capacity (from timesheets) as a field, to calculate time tracked/time capacity

so the data is there, and some of the functionality is there, just not in all places or in a way that I can use to report easily
