The dispersion_plot() method uses pylab.show() to display the data (in another window). Only when you close that window the interactive interpreter becomes responsive again. If you didn't overlook that window: do you run into the same problem with >>> import pylab >>> pylab.plot([1, 2, 3], [3, 1, 2]) [<matplotlib.lines.Line2D object at 0x2d713d0>] >>> pylab.show() ? If so, choose another backend. I've not tried, but it seems straight- forward, see <http://matplotlib.org/faq/usage_faq.html#what-is-a-backend>
