Chrome (not Grafana) crashes - probably you are hitting some Chrome app limits (probably memory and OS has killed tab process). Don’t select RAW data, but use time aggregation, so you browser won’t need to process a lot of datapoints.
When I added it to my query I don’t get any data points. Here is my updated query:
SELECT "28V output current" * "28V output voltage" AS "28V Output Power", "Battery Current" * "Battery Voltage" AS "Battery Power", "I BOP" * "V BOP" AS "BOP Power", "Battery charge status" FROM "power" WHERE ("machine_id" =~ /^$machine_id$/) AND $timeFilter GROUP BY time(24h)
Oh, you havn’t told it what to do with the grouping, you need to specify mean or other aggregation SELECT mean("CAT 1") FROM ...
or max or min or whatever you want.
