Description tombrown9501 2024-02-16 05:00:42 UTC
SUMMARY
When selecting Automatic Y Data Range for my temp sensor line chart the program picks Y values that aren't as helpful as they could be. 

Example 1 - 
Chart created to track system temps other than CPU. Temps hold steady from 25C to 45C and Automatic Y Data Range chooses -273C  (which is about a tenth of a degree above absolute zero) to 85C. 

Example 2 -
Chart created to track CPU temps. Temps are at around 45C to 60C and Automatic Y Data Range chooses 0C to 56C, sometimes clipping the top of the graph when temps hit 60 very briefly. 

I would expect the functionally of this option to choose a Y value 5-10 degrees above the highest temp value recorded in the past 5 or so minutes and a Y value 5-10 degrees below the lowest temp value recorded in the past 5 or so minutes. I think that might be a better framework to have for this functionality.

Thanks!

I'll add that some people prefer that lower graph values to always be at zero there could be an additional checkbox for this.
