Bins

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.

Sets the end value for the x 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.

Sets the size of each x axis bin.

Default behavior: If nbinsx 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 nbinsx is provided, we choose a nice round bin size giving no more than that many bins. For date data, use milliseconds or M 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.
