I vehemently disagree that 0 should be the baseline. That would make absolutely no sense for this plot. I would use something like the average or median of the relevant temperatures as baseline. Using 0 as baseline gives you huge columns and does not highlight the big step at all. I would rather have relative value changes to the lowest temperature I chose to display, so in this case: 0 0.12 0.33 0.50 0.51 1.49

3D columns are bad of course, but that is neglible.
