Perhaps someone else can help as I feel I am being particularly dense.
for i in xrange(numcols):
ax.plot([np.mean(mass[:,7]) for i in xrange(numcols)],
np.arange(numcols), label=i)
This gives you what I think you said, but really don't think this is what
you mean as it seems a strange thing to want to do.
sorry i couldn't be of more help
