The only way is to either increase width of the window or change the sampling rate in HWiNFO settings.
Another alternative would be to log all sensor values using the logging function and then examine the results using a tool like this: https://www.hwinfo.com/forum/Thread-LogViewer-for-HWINFO-is-available or any other tool (i.e. Excel) that can import Comma Delimited Files (CSV).
lol, I didn't even think that just resizing the window would widen the x-axis, thank you, that helped. And I checked out that log viewer, it's pretty handy too.
