it works great for 100 mhz or less spans but i am trying to do a scan from 1:1500 mhz and it simply outputs a blank plot? is there any way to modify it to work this way?? i know nothing of the rust language or id try im desperate to get a plot over this range.

It should work OK for wide ranges like that. You may have been running into an issue where a long-running sweep has chunks at plotted at different timestamps, leaving a lot of blank space between them? Recent versions of hackrf_sweep have a -n flag that keeps the timestamps the same and resolves that.
