Just a follow-up: I managed to interpolate this problem away...
interpolated = []
iinds = []
for i in range(len(stockData.rinds)-1):
interpolated.append(s[stockData.rinds[i]])
iinds.append(stockData.inds[i])
interpolated.append((s[stockData.rinds[i]]*3. +
s[stockData.rinds[i]+1])/4)
iinds.append(stockData.inds[i] + 0.25)
interpolated.append((s[stockData.rinds[i]] +
s[stockData.rinds[i]+1])/2)
iinds.append(stockData.inds[i] + 0.5)
interpolated.append((s[stockData.rinds[i]] + 3.*
s[stockData.rinds[i]+1])/4)
iinds.append(stockData.inds[i] + 0.75)
interpolated.append(s[stockData.rinds[len(stockData.rinds)-1]])
iinds.append(stockData.inds[len(stockData.inds)-1])
interpolated = array(interpolated)
ax.fill_between(iinds, interpolated, 50-thresh,
where=interpolated<50-thresh, color=color, alpha=0.3 )
It would be nice to see this taken care of intelligently inside the
fill_between routine, but I wouldn't know how to do it for the general case.
Maybe this post will allow future users with a similar problem to find their
answer.

Subject: Bug in Fill_Between?
Is this a bug in fill_between, or is there a known workaround?
In the attached picture, I'm calling fill_between as follows, and I can't fill
the entire area between the line (50+thresh) and the signal, s. I realize that
the areas that aren't filled are boundary conditions, but there should be some
sort of interpolation I can do to fix this I would think...
ax.fill_between(stockData.inds, s[stockData.rinds], 50+thresh,
where=s[stockData.rinds]>50+thresh, color=color, alpha=0.3 )
So for example: stockData.inds = range(6), s[stockData.rinds] =
[20,30,70,80,40,20] and thresh = 0. I need the areas filled with color where
stockData.rinds is greater than 50. It does fully fill in the xrange(2,3), but
the border conditions xrange(1,2) and xrange(3,4) are not fully filled under
the line.
I had the same problem with fill_over and was hoping it would be resolved with
the move to fill_between. Any ideas?
