Issue with correct Module plot_dwnlow_scans

[danhamill]

I moved this from #43 because it is a different issue.

When running the test, a TypeError gets thrown in the correct module.

@philw6 could you provide some information about your machine? Matplotlib version, anaconda distribution, and numpy version?

[philw6]

I'm running Windows 10 Home on an i7 64bit with 8GB RAM. Latest Anaconda2 (32bit). latest numpy (1.11.3). latest matplotlib (2.0.0).

The
ufunc 'isfinite' not supported for the input types
error is related to matplotlib and can be removed if you comment out the

plt.axis('tight')

commands in C:\Users\Phillip\AppData\Roaming\Python\Python27\site-packages\PyHum_pyhum_correct.py
