docstr: Sets the starting value for the x axis bins. Defaults to the
  minimum data value, shifted down if necessary to make nice
  round values and to remove ambiguous bin edges. For example, if
  most of the data is integers we shift the bin edges 0.5 down,
  so a `size` of 5 would have a default `start` of -0.5, so it is
  clear that 0-4 are in the first bin, 5-9 in the second, but
  continuous data gets a start of 0 and bins [0,5), [5,10) etc.
  Dates behave similarly, and `start` should be a date string.
  For category data, `start` is based on the category serial
  numbers, and defaults to -0.5. If multiple non-overlaying
  histograms share a subplot, the first explicit `start` is used
  exactly and all others are shifted down (if necessary) to
  differ from that one by an integer number of bins.
  
  The 'start' property accepts values of any type
  
  Returns
