This is an order of opertations problem. The call to "plot_date" sets
the DateFormatter, overriding your choices. You need to set your
custom formatter after the call to plot_date:
ax.plot_date(dates, vals, 'bo')
ax.xaxis.set_major_formatter(DateFormatter('%b %d'))
ax.yaxis.set_major_formatter(FormatStrFormatter('%3.0f KBps'))
This is an annoyance that we can fix by setting the date formatter
only if the current formatter is *not* a date formatter instance.

That's odd. I would think that it makes more sense to set the format *before* the data is plot, not after.
ax.plot_date(dates, vals, 'bo')
ax.xaxis.set_major_formatter(DateFormatter('%b %d'))
ax.yaxis.set_major_formatter(FormatStrFormatter('%3.0f KBps'))

Probably a good thing for people like me who have never used Matlab.
