Any reason for naming this _inputLength? Parcoords and splom use _commonLength to stash their common dimensions[i].values length - which I guess is a little different than the finance trace case here and the regular traceOut._length used in (all?) other traces.

This will be converted to _length when I de-transform these traces, but I didn't want to use that (or _commonLength) here since the post-transform traces have different lengths.
