Hi Colin,
Matplotlib is a third-party library, so you may also consider asking
the matplotlib folks.
>From a brief look at:
http://matplotlib.org/1.4.2/users/pyplot_tutorial.html#working-with-multiple-figures-and-axes
it appears that you can override the default axis, and specify xmin,
ymin, xmax, and ymax values.
http://matplotlib.org/1.4.2/api/pyplot_api.html#matplotlib.pyplot.axis
For your particular case, you may want to just limit your x axis, in
which case xlim() might be appropriate.

If all else fails, just filter your data before submitting it to the
grapher. The program loads data here, using loadtxt
(http://docs.scipy.org/doc/numpy/reference/generated/numpy.loadtxt.html):
data = np.loadtxt('2014_12_04-16_30_03.txt',skiprows = 0 ,usecols = (0,1))
and it's just a numpy array: you can manipulate numpy arrays. See:
http://stackoverflow.com/questions/26154711/filter-rows-of-a-numpy-array
as an example of an approach.
