OK JJ, trying to be more descriptive.
To run the code, you have to get nasafile.py and add this into your
PYTHONPATH, later get dccn_plot.py and 09_03_26_11_36_15.dmtccnc.combined.raw
file. nasafile.py has the NasaFile class to read this ascii file.
run as ./dccn_plot.py 09_03_26_11_36_15.dmtccnc.combined.raw
I have changed the code as you suggested. Here is the result:

Two things I notice, right y-axis label is gone, and latter the top x-axis
nicely added there but it a replicate of bottom x-axis. Doing this:
from matplotlib.dates import DateFormatter, HourLocator
locator = HourLocator()
pary.xaxis.set_major_locator(locator)
formatter = DateFormatter(r'$%H^h$')
ax2.xaxis.set_major_formatter(formatter)
results with my IPython session crashed:
RuntimeError: Locator attempting to generate 216001 ticks from 41000.0 to
50000.0: exceeds Locator.MAXTICKS
I want to be able see in this fashion:
I[3]: current_axis = gca()
I[4]: current_axis.xaxis.set_major_formatter(DateFormatter('%H:%M:%S'))
but this returns the bottom x-axis and changes them to all 00:00:00.
