Bug in Fill_Between?

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]]*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)



= 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.

Is this a bug in fill_between, or is there a known

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?
