I think that’s the clue. I’ve always had MapDB set as my default. I tried switching to InfluxDB as the default and the chart came up blank. I switched the default to rrd4j and the charts started working.
I need to think a bit on this to figure out how the confusion I fell into can best be avoided:
- clarify in the docs
- require rrd4j to always be there
- open an issue to see how to make it work with other database
- something I can’t even think of right now
But I’m happy to finally see charts when I click analyze. Thanks!
