Thank you Thomas, this results in
but how to get a JSON map of lists here? I am trying:
select
day AS day,
jsonb_agg(completed) AS completed,
jsonb_agg(expired) AS expired
from (
SELECT TO_CHAR(finished, 'YYYY-MM-DD') AS day,
count(*) filter (where reason in ('regular', 'resigned')) AS completed,
count(*) filter (where reason = 'expired') AS expired
FROM words_games
WHERE finished > CURRENT_TIMESTAMP - INTERVAL '2 week'
GROUP BY day
) t
GROUP BY day
ORDER BY day;
day | completed | expired
------------+-----------+---------
2021-02-08 | [481] | [155]
2021-02-09 | [770] | [263]

While I would actually need:
{
"day": [ "2021-02-08", "2021-02-09", ... ],
"completed": [ 475, 770, ...],
"expired": [ 155, 263 , ...]
}
And then I could feed the data into the Chart.js shown at the bottom of my web page https://slova.de/top
Currently I do a simple SELECT query and construct the JSON map of list in the Java code of my servlet
Thank you
Alex
