Matplotlib for python solves this with a SymLogScale, which is allows you to chart (-10 ^3, - 10^2,..., 10^2, 10^3) in the way that you'd expect. It does this by being linear between two small limits (to avoid doing log(0) and upsetting the mathmos) and showing sign(x) * log(abs(x)) elsewhere.

You can probably do the transformation yourself directly on your data, and then do the inverse transformation relatively easily for your tool tips.
