Note : While this solution worked, I found that it was very slow because of the time required to load Python so I ended up reverting back to GNUPlot, see here for further details : http://realgonegeek.blogspot.co.uk/2014/01/interfacing-cc-to-gnuplot.html.
All you need to do is take the earlier C example, change the Python method from PrintArray to PlotArray and recompile.
def PlotArray (a):
import matplotlib.pyplot as pp
from matplotlib.font_manager import FontProperties
import numpy as np
p1, = pp.plot (a, label = "line 1", color='red')
ax = pp.subplot (111)
box = ax.get_position ()
ax.set_position ([box.x0, box.y0, box.width * 0.85, box.height]) # Shink x axis to fit legend
fontP = FontProperties ()
pp.legend (loc=2, prop = fontP, fancybox = True, bbox_to_anchor=(1, 1.0))
pp.ylim (ymin = 0, ymax = 10)
c = 0
