possible layout bug


I found what I believe is bug in matplotlib.
The program

    from matplotlib.matlab import *
    from math import sin

    x=map(lambda tt:sin(tt), t)

    xlabel("total time")
    ylabel("tatil tome")
    title("titol tame")

    show ()

displays a graph, where the xlabel is shifted to much down. Only the
upper half of the xlabel is still visible, the lower half is outside
the visible area.

Is this a bug? Or do I need to somehow manually reserve space for the
display of the xlabel?

All the best,
