scale_errors_by in Hist1d's plot is bugged
... it moves the error bands up or down as opposed to scaling them.
A new release to set color bar kwargs
Would be a nice feature
Plot on specified axis
Useful for making subplots
TProfile like options
Something like
mh.Histdd(...)
means, errors = mh.profile(axis=0)
and
mh.profileplot(axis=0)
maybe even some fitting shortcuts?
Multihist bug in assert len(coordinate_arrays) == self.dimensions
With some update (of numpy, I believe), multihist failed at lookup (line 682) with:
682 assert len(coordinate_arrays) == self.dimensions
Casting hist_ravel spesifically as float avoids this problem, diff of my local fix:

Floating point error in the j2000 event time
This results in a value of t out of range of self.t_start and self.t_end. One solution is to do
np.clip(t, self.t_start, self.t_end)
to enforce t to be in the correct range. Might add a warning before to check how far out of bounds t is.
Clip to range option
It would be nice if there was an option to clip input data that is out of range of the histogram to the nearest bin in range.
