Graphana misleading data representation

Hi, i got unsolved mistery that i can’t understand.
Our data is in a PostgreSQL database. This graph is using log table of our completed crawler (it can be either completed, failed, timedout or died).
For the exemple below, the inteval is 10min for a timefilter of the last 7 days
Graphana render the only fail of the day, over full day like if they were many failed in a row.

  • What Grafana version and what operating system are you using?
    Unsure, don’t know where to find the graphana version. Pop’OS

  • What are you trying to achieve?
    Rendering a graph showing the the percentage of success of our process.

  • How are you trying to achieve it?

SELECT
$__timeGroupAlias(crawler."timestamp",$__interval,0),
  COUNT(CASE WHEN status='DIED' THEN 1 END)::float/NULLIF((COUNT(CASE WHEN status  ~ '(COMPLETED|FAILED|DIED|TIMEDOUT).*' THEN 1 END)::float),0)*100 as "%DIED",
  COUNT(CASE WHEN status='FAILED' THEN 1 END)::float/NULLIF((COUNT(CASE WHEN status  ~ '(COMPLETED|FAILED|DIED|TIMEDOUT).*' THEN 1 END)::float),0)*100 as "%FAILED",
  COUNT(CASE WHEN status='TIMEDOUT' THEN 1 END)::float/NULLIF((COUNT(CASE WHEN status  ~ '(COMPLETED|FAILED|DIED|TIMEDOUT).*'  THEN 1 END)::float),0)*100 as "%TIMEDOUT",
  COUNT(CASE WHEN status='COMPLETED' THEN 1 END)::float/NULLIF((COUNT(CASE WHEN status  ~ '(COMPLETED|FAILED|DIED|TIMEDOUT).*'  THEN 1 END)::float),0)*100 as "%COMPLETED"

LEFT JOIN biz on biz.id = biz_id
LEFT JOIN application ON crawler.application_id = application.id
LEFT JOIN vendor ON application.vendor_id = vendor.id
WHERE
  $__timeFilter(crawler.timestamp) AND NOT biz.module IN('Pending') AND vendor.name IN($vendor_name) AND biz.name IN($biz_name)
