Here's how I modified my code:
sci_fmt = FormatStrFormatter("%.2f")
fig = figure()
top_axes = subplot(211)
top_axes.xaxis.set_major_formatter(sci_fmt)
#plot_date(times,kurts,fmt='b-')
#plot_date(times,kurt_sm,fmt='r-',label=("Hamming 1-sec FWHM"))
plot(times,kurts,'b-')
plot(times,kurt_sm,'r-',label=("Hamming 1-sec FWHM"))
I then restarted 'ipython -pylab' because I've noticed that date 
formatting problems seems to linger even after a code change.  However, 
I see no change in behaviour.  I can get six 1-sec ticks across my 
plot.  If I expand the plot any more, the ticks disappear.

Regards

Tom
