fifo plot signal python with time-series data

Question

I have a problem with the xmgrace visualization. I have created the fifo which will store the data to be able to do real time series. The problem is that the fifo archive contains all 3 signals and as I run the commands in the terminal I can't find a way to separate the 3 signals.

I run:

xmgrace -npipe fifo & python file.py >> /tmp/1 && /tmp/2

while[1]; do echo "read\"/tmp/1\"">fifo;echo autoscale>fifo;echo redraw >fifo; sleep 1; do echo "read\"/tmp/2\"">fifo;echo autoscale>fifo;echo redraw >fifo; sleep 1; done

Any ideas??
