Welcome @kong62 to the Grafana forum.
Can you share your query / screenshot of Total QPS?
And within one panel, can you set up Query A as Total QPS, Query B as Max QPS (but probably modifying your Prometheus query to do the “Max” calculation), then use a transformation to calculate Total QPS / Max QPS, like this?
Or perhaps you can use two transformations: one to get the Max QPS and a second one as described above?
