Problem with different values according to interval

Hi, I have a question about the dashboard interval.

① The max value in the graph panel and the max value in the gauge panel are different.
② Plus, when I change the time range, in other words, the max value is different when the interval changes.


For example of ①, the max value of graph panel is 2.23 but gauge panel’s 1.82.
Even if they refer same thing.


For example of ②, the max value is different when I zoom the graph.

I always appreciate your help.
