I don't know which update it was that broke it, but this used to work:
fig = pylab.figure(1,figsize=(8,5))
ax = fig.add_subplot(111, autoscale_on=False, xlim=(-1,5),
t = numpy.arange(0.0, 5.0, 0.01)
s = numpy.cos(2*numpy.pi*t)
line, = ax.plot(t, s, lw=3, color='purple')
This used to plot an arrow under the text 'no data' but above the main plot. Now this arrow does not appear unless at least part of it is within the plotting area. Change one of the '3.1' in the code above to, say, 3.0 and the whole arrow is displayed. Is this a bug or is there a new way of achieving what I want?
Thanks for your help already!
