Matplotlib scatterplot; colour as a function of a third variable
...e record, you can apply ALPHA as a colormap if you provide an (n,4) shaped array as c argument, with alpha values in the fourth column. If third variable is Z, with shape=(n,1), then colors = numpy.hstack((numpy.zeros_like(z), numpy.zeros_like(z), numpy.ones_like(z), z/z.max())) gives a very nice e...
