I think it is to support for small ranges on top of very large numbers. I think the fix you suggest below will work for now (I had to make an additional change to format the offset label correctly, svn 2668), and I can clean up the default formatter later. I don't want to rush through that. People have asked for on more than one occassion for engineering notation: tick labels that read 2x10^-5, they would read 20x10^-6, and I think this would work with the shorter string formatting. > I don't know what the right answer is: using the default formatter is > usually irritating when plotting dates, since you often want a finer > resolution than you get with the tick formatting (eg if the ticks are > formatted to the nearest day, you may want to see H:M:S when > interacting).
