Unevenly spaced data

Basic demonstration of pcolor, which can deal with unevenly spaced data

Note

Right now, we just do this with real/imaginary, but in principal, it should be easily possible to extend this to use domain coloring (and to use it in the main DCCT method)

y = psp.nddata(3 * r_[-5, -2, -1, -0.5, 0, 0.5, 5], "y")
z = plt.exp(-((y - 2) ** 2) - (x - 0) ** 2 / 2) + 1j * x
