The easiest way to plot an eye diagram would be to create a new eye diagram sink. The plot widget that we're using behind the scenes is pretty straight forward to use. I'd suggest taking a look at gr-wxgui/src/python/scopesink.py as a starting point. It's got a bunch of extra GUI knobs that you might not need. Take a look at the format_data function. That's where the actual lines to be drawn are created. The plot widget has decent inline docs. See gr-wxgui/src/python/plot.py.
