I've updated the dashboard to include a "Users last calendar month" graph, which provides the number of distinct users that have participated in translation activities in the most recent month.

Load Time Issue
This new user graph is taking significantly longer to load than the other graphs on the dashboard (anywhere from 90 seconds to 2 minutes depending on available bandwidth) and sometimes results in a timeout error. This is because the user data needed for this graph requires querying mediawiki_history, which takes longer to run compared to the other graphs that come directly from the edits_hourly dataset available in Superset. The edits_hourly dataset does not currently include data on the number of unique users.

If we find that this load time frequently results in timeout errors, there are a few options we can take to obtain this data more efficiently:
(1) Add more conditions to limit the amount of data to be queried. For example, limiting the time range, languages, or namespaces that are queried. This could be done easily by adjusting the query; however, we would likely need to apply the same conditions to the other charts so the data is consistent.
(2) Once T307883 is resolved, update the dashboard to include user data from the new editors_daily dataset, which will run as quickly as the other charts on the dashboard. This task is currently deprioritized so it will likely not be available soon.
(3) Create a separate smaller dataset of aggregated translation data to query and set up a job to automatically rerun the query every month. This will require some more time to set-up but would greatly reduce the load time and would also be useful for other planned additions to the dashboard such as newcomer retention T226170. A task for this work has already been created (T287306).

Dashboard Filter Update
The filters are now located on the right side of the dashboard (See screen shot below). The previous Filter Box was replaced with built-in dashboard filtering as part of the recent Superset update but the filters should still work as expected.
