Issue with thermostat display graph

Not sure of this is a new problem or long running one that I’m just noticing.

If I view the graph for my thermostat I can see a yellow line representing the set temperature and a shaded blue beneath the line showing when the system was on.

But the Y-axis is set such that it locks to the lowest set temperature for the day, which makes the yellow line touch the X-axis and thus I can’t see shaded blue beneath that area to see when the system was running.

On version core-2026.8.3

I think it’s always been an issue, though it doesn’t always manifest (I’m not sure how the chart ends up with its exact margins, but sometimes it has enough margin). Probably would be good to have a frontend issue open for this.
