I think we can add hue and faceting (row, col) support to hist. I am surprised step doesn't support hue already since iot sets a few kwargs before calling line.

Here's the error for step with hue. I think we can safely call this a bug. ``` ~/python/xarray/xarray/plot/plot.py in step(self, args, kwargs) 461 @functools.wraps(step) 462 def step(self, args, kwargs): --> 463 return step(self._da, *args, kwargs) 464 465

~/python/xarray/xarray/plot/plot.py in step(darray, where, drawstyle, ds, args, kwargs) 369 drawstyle = "steps-" + where + drawstyle 370 --> 371 return line(darray, args, drawstyle=drawstyle, **kwargs) 372 373

~/python/xarray/xarray/plot/plot.py in line(darray, row, col, figsize, aspect, size, ax, hue, x, y, xincrease, yincrease, xscale, yscale, xticks, yticks, xlim, ylim, add_legend, _labels, args, *kwargs) 297 # Remove pd.Intervals if contained in xplt.values and/or yplt.values. 298 xplt_val, yplt_val, xlabel, ylabel, kwargs = _resolve_intervals_1dplot( --> 299 xplt.values, yplt.values, xlabel, ylabel, kwargs 300 ) 301

~/python/xarray/xarray/plot/utils.py in _resolve_intervals_1dplot(xval, yval, xlabel, ylabel, kwargs) 509 510 # Convert intervals to double points --> 511 if _valid_other_type(np.array([xval, yval]), [pd.Interval]): 512 raise TypeError("Can't step plot intervals against intervals.") 513 if _valid_other_type(xval, [pd.Interval]):

ValueError: could not broadcast input array from shape (100,7) into shape (100) ```

@jaicher PRs to fix these are very welcome!
