I’ve added a column to the "Merit per Post" tab called nMeritedPosts, that counts the distinct number of posts merited within the given board and month.

Notice that the toll is counting the number of posts that have been merited withing the meriting timeframe, not withing the posting timeframe. That is to say, I’m counting based on when the meriting event takes place, not when the posting event takes place.

Note: I'm updating the Dashboard now. Give it 5-10 minutes or so to complete.

Note2: Weird side-effect: updating the board seems to have replaced the whole Dashboard with a Viz (single tab). I’ll try to look into it later on. Solved.


Edit 20230604:
The next Merit Dashboard update will be delayed a few days. I’ll probably manage to do it next Tuesday/Wednesday (instead of this Friday).

I really don’t have much control over the sorting capabilities. I’ve played around with the sorting capabilities on the tab for a while, and I’m not sure exactly what you are encountering. If you’d like to provide a user case, so that I replicate the behaviour, I’ll get a better grasp of the issue.

There’s the old <CTRL>+Z to take the filtered selection one step back at a time, and at the bottom right of the screen the left pointing arrow "<-" should perform the same action. There’s also an icon similar to "|<-" which undoes all the steps altogether, and should therefore revert the filters to a situation similar to when you load the dashboard for the first time in the session.

Update 07/04/2023:

The dashboard gives you access to anyone’s complete merit history in the TX tab, surpassing the 120 day limit.

thanks for the updates
I started seeing this dashboard very often
it is very beautiful and full of data, you can understand a lot by looking at the graphs

thank you   when i deserve, some are yours guaranteed

I briefly remember I had to update it after I had the month’s complete data … but forgot to do it (again) nevertheless.

It’s now updated with data running up to last Friday (april 2023 is therefore partial).

Edit:
Thanks. I’ve now taken it into account, though in my case, the only place this detail level appears is in the "Local Board post count evolution" tab. There, I derive the data from a snapshot of the forum’s monthly stats, which are not modified retrospectively for obvious reasons. Changes will therefore be move visual next month, though historical month’s data won’t get its subsection reassigned.
