If the other colours are deltas, they all need to start at the x-axis then. Positive or negative. Not just the negative. For all the other buildings, you add the deltas onto the end of the last bar. So when all deltas are positive, the bar increases in length. Sure, doing that with negative deltas means the other colours will overlap the blue and be difficult to distinguish, but it would be consistant. Having the positive delta's added at the end of the last value but the negative deltas ignoring the previous value and just starting from zero is inconsistant and makes the graph meaningless for comparison. Actually, even the negative delta's are inconsistant. You only start the first negative delta at zero, but then you add the next deltas onto the end of the last one...

So the graph is consistant and meaningful, I think you ought to put the negative delta's adjacent to the positives. So the bar goes up like normal, adding the deltas to the end of the bar, then when it becomes negative, bring the deltas down the bar adjacent so you can still see all the data, but in line.

Else you need to have all deltas start from 0, which would not be helpful.
