The example above works for me just fine (in ipython): In [1]: import pylab In [2]: import numpy In [3]: t = numpy.arange(0.0, 1.0+0.01, 0.01) In [4]: s = numpy.cos(2*2*numpy.pi*t) In [5]: pylab.plot(t, s) Out[5]: [<matplotlib.lines.Line2D at 0x3c36310>] In [6]: pylab.show() # At this point a plot of cos(t) appears as expected Have you customised your matplotlibrc file?
