You can transpose your inputs.  For numpy arrays: x = x.transpose()

Subsequent calls to plot will call the autoscaler, so either you need
to set the xlim *after* all the plotting commands or turn off
autoscaling entirely by passing the autoscale_on=False property to the
axes, eg

plt.gca().set_autoscale_on(False)
