You can render matplotlib figures to PIL using following code:

figure.set_size_inches(float(shape[0]) / figure.dpi, float(shape[1]) /
figure.dpi)

canvas = matplotlib.backends.backend_agg.FigureCanvasAgg(figure)
canvas.draw()
image_string = canvas.tostring_rgb()

image = Image.fromstring("RGB", shape, image_string)

fwiw,
