Where is there some documentation for SignalPlotter (the python version; I've decided that python is the way to go for this simple plasmoid)? I have a draft of the DataEngine written (doubtless with bugs, but I understand the principle so it's basically just debugging that's needed). I couldn't find an example of a python plasmoid that uses a SignalPlotter the way that I could for the DataEngine, though, so I have nothing to steal and no documentation to get an understanding of what SignalPlotter does and how to make it do what I want.
