Are currency charts the only type of chart where it is acceptable for the X axis to not start at zero?

Share prices too. Especially if you want to suggest a company is failing when its share price has 'dived' 2p in a couple of hours (ignoring that the price is £187 per share).

I remember someone on Cake Stop posting a graph that was supposedly showing a financial catastrophe but when looking at the graph it was split into fractions of a penny (I think it may also have had a distorted y axis). Can't recall who it was but could probably guess.

Most complaints are about the y axis. Anything plotting time will not start at the big bang.

Obviously the legendary data journalist at the FT thinks starting the y axis at anything you like is fine. I'd say you need to establish what the base is. There is no point plotting a patient's temperature in kelvin.

The base for shares is 0.

Obviously in this case, you weren't actually looking for a response.

All sorts of things ... or do you mean y-axis?

I carelessly assumed that that was what he meant. Must learn to read.

Bad Graphs was a standing joke on Cake Stop. So much so that if either the X or Y axis started at zero, it would be remarked on. We had a party if both did.

I agree that there is generally a more compelling argument for starting the y axis at zero, and that's what I intended.

But in fairness I think the FT and Twitterati have an aptitude for distorting data using either axis.
