Perhaps you are seeing a problem where your previous plot is not
cleared and so you see both on the same axes?  The format strings
works for me as expected

    import pylab
    import datetime
    d1 = datetime.date( 1995, 1, 1 )
    d2 = datetime.date( 2004, 1, 1 )
    delta = datetime.timedelta(days=365)

    dates = pylab.drange(d1,d2,delta)

    y = pylab.rand(len(dates))
    pylab.plot_date(dates, y, 'r-')
    pylab.show()
