Graph diffeerence when switching between $__interval and directly providing time window

I see a difference in graph display when I switch between $__interval and directly providing time window value to increase function.

This is with $__interval

This is when I provide time window value in query directly.

Why this difference?
Btw, value I use is 1m in both cases. First one seems to be better. In second case, it shows more than 5 bars between 22:36 and 22:38. As window is 1m, so number of bars seems to be more than expected.
Or do I understand it all wrong.

Hi,

It’s seems that the first case it applies Mean on your data but the second it displays data points. Try to test if this is the case.

Hope it helps.

Good Luck
