Temperature metric chart reads incorrect maximums and minimums

I have temperature sensors placed around our building watching things. When I look at the service graph with a 4 hour time window, the bottom of the graph displays the minimum and maximum read values.

If I choose to view the last 25 hours graph, the maximum and minimum change but not in the way I would expect. The minimum temp in the case of the sensor I am looking at now with a 4 hour window is 52.5 degrees, but if I look at a 25 hour window, the minimum changes to 62.4, which makes no sense as the last 4 hours is a part of the last 25 hours.

I can see the graph is smoothed to be able to fit a larger window on the display, but why does the read out minimum and maximum appear to change with the graph smoothing?

I do see that at 4 hours the graph seems to choose 1 minute increments and at 25 it chooses 5 minute increments, but this loses a ton of granularity as seen. Is there a way to have these numbers show the true minimum and maximum levels over longer periods of time?

In your second graph if you click on the “Minimum” left of the bold “Maximum” you will see the minimum values in this 5 minute timeframes.

Perfect. Apologies for missing that and thank you for the clarification.
