This gist is based is on an pull-request to the flor repository by Arne de Laat.
The plugin generates nice look logarithmic ticks, e.g. [10⁻¹, 10⁰, 10¹, 10², 10³]. If there are not to many ticks it also creates some in between: [10⁰, 5x10⁰, 10¹, 5x10¹, 10², 5x10², 10³]. If the data to be plotted is all between two powers of ten the currently default tick generator and formatter are used instead.
Mainly tested in latest versions of Safari, Firefox and Chrome. Possibly still buggy for special cases.
