> It isn't really disingenuous. It's become fashionable to claim that "all graphs should start at zero", but that's not necessarily how you display data.

Not all graphs no, but for histograms which are meant to compare quantities, maybe yes. See the other discussion in this thread.

The kind of false impression that at least I get when I look at this graph is that the grades were multiplied by a factor ~1.3 over the past 20 years when they were only multiplied by a factor 1.06. For anyone familiar with GPA, this is misleading.
