Yes, it looks like the graph in the Stat panel (Grafana v12.0.1) auto-scales to the min/max of the current data, not a fixed 0–100% range. That’s why the sparkline height and position can be misleading — sometimes 100% even appears in the middle. This makes percentage values hard to interpret at a glance. It would be great if Grafana added options to align the sparkline graph — for example, fix it to a 0–100% scale or add a visual reference line for 100%.
