              Sets the end value for the y axis bins. The last bin
              may not end exactly at this value, we increment the bin
              edge by `size` from `start` until we reach or exceed
              `end`. Defaults to the maximum data value. Like
              `start`, for dates use a date string, and for category
              data `end` is based on the category serial numbers.
          size
              Sets the size of each y axis bin. Default behavior: If
              `nbinsy` is 0 or omitted, we choose a nice round bin
              size such that the number of bins is about the same as
              the typical number of samples in each bin. If `nbinsy`
              is provided, we choose a nice round bin size giving no
              more than that many bins. For date data, use
              milliseconds or "M<n>" for months, as in `axis.dtick`.
              For category data, the number of categories to bin
              together (always defaults to 1). If multiple non-
              overlaying histograms share a subplot, the first
              explicit `size` is used and all others discarded. If no
              `size` is provided,the sample data from all traces is
              combined to determine `size` as described above.
          start
              Sets the starting value for the y 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.
