@mcigorli,
Auto-calculated axis range depends on multiple factors which include values of entire dataseries as well. From the screenshots shared, we are unable to predict the exact use-case / scenario properly. Hence, can you kindly create JSFiddle reproducing the issue you are facing & share it with us so that we can look into the code / chart-options being used, understand the scenario better and help you out?
