Reverse loss shows 10000%

See https://ps-mesh.perf.ja.net/grafana/d/07fde0de-9fb7-581a-b653-83ca056ae7aa/dd5fcc39-f3ef-54a2-b901-8b6ce95208a5?var-source=ps-london-lat.perf.ja.net&var-dest=pygrid-sonar2.lancs.ac.uk&orgId=1&from=1728569818541&to=1728643451531&var-source_ref=All&var-dest_ref=All for an example.

It looks like there's no loss in practice.

Looks like the y axis has a max of 10000%, but all the loss values are 0. We can adjust the max value shown for that axis.

OK, not sure why a percentage loss axis would ever be more than 100 :)

We saw this also during workshop and I can confirm it in a fresh archive installation too. Possibly Grafana must have changed some behavior as now indeed it doesn't automatically scale the Y axis but prints this max value.
Grafana dashboard templates would have to have max value set explicitely now

@arlake228 Is there a way to permanently set this value through the agent or template? Modifying just a Grafana page is overwritten each time agent builds the visualization.

Any plans for the fix? It's a very annoiyng issue
