plotsweep's Issues

is there a way to get it to work over a larger range?

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.

Allow for slightly older rust versions

Currently Rust 1.50.0 is required but we could support some older distro-packaged versions with fairly minor changes
