# make an agg figure
fig, ax = plt.subplots()
ax.plot([1, 2, 3])
ax.set_title('a simple figure')

# grab the pixel buffer and dump it into a numpy array
X = np.array(fig.canvas.renderer._renderer)

# now display the array X as an Axes in a new figure
fig2 = plt.figure()
ax2 = fig2.add_subplot(111, frameon=False)
