You said ""Pico suggested 'bar graphing' but I dont know how to yet.""
Is that in the "web help" section of Pico?
I don't know which Pico product you are using, but the 4000 series devices are introducing the capability to "grap" frequency signals. Although initially it only allowed a max of 2kHz, but I think it has been increased to 20kHz in the recent software update. You can find the frequency option in the "coupling" drop-down box. Where you used to see AC or DC, you know have the Frequency option too!
I haven't had a chance to play yet, but it looks like another great feature has been added to the package.
Cheers
