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.
