Neal,
   I like the idea of a faster np.histogram / histogramdd;
but it would have to be compatible with numpy and pylab
or at least a clear, documented subset (doc first).

Some Wibnis, wouldn't it be nice ifs, for WibniHistogram:
- gui with realtime zoom / upsample / smooth: must exist, physicists ?
- adaptive binning, e.g. percentiles then uniform
- interpolate: fill holes, then *linear or spline

+= data is nice, but seems orthogonal to histogramming --
why not just subclass histogram ?

cheers
