The explenation for the unified class group graph is not clear

This is what I see on the Explore:

And this is what I see in View (and dashboard too)

In the latter case legend doesn't match the plot -- legend shows blue compaction to consume 60% and other classes to be minor, while on the plot itself there are two -- purple and orange -- plots that consume 80%+, which is not quite true. The explore page shows coordinated legend and plots

Scylla Monitoring version - 4.6.0

@xemul, have you noticed that in the dashboard, it's both group and class?
your Prometheus query should be:

sum(rate(scylla_io_queue_consumption[1m])) by (cluster,class, iogroup)

I've opened grafana/grafana#82417 we should try to upgrade and see if the problem get solved in Grafana

Sorry, I forgot that it's a stack graph, the idea here is to see how it all adds up to 100% The documentation should be better
