Live graph data from slave

Hi all,
Is it possible to graph data coming from mavproxy’s slave connection (one of the outs)?
Seems like it can only graph data coming from the master.
Though it saves data from slaves to tlog.

The setup has a companion computer sitting on one of the outs, and I want to graph live data coming from it.

Additional question is if it’s possible to forward messages between outs? Like when you have companion computer and ground station sitting on the outs.
