Table.bin(*columns, **vargs)[source]

Group values by bin and compute counts per bin by column.

By default, bins are chosen to contain all values in all columns. The following named arguments from numpy.histogram can be applied to specialize bin widths:

If the original table has n columns, the resulting binned table has n+1 columns, where column 0 contains the lower bound of each bin.

Args:
columns (str or int): Labels or indices of columns to be
binned. If empty, all columns are binned.
bins (int or sequence of scalars): If bins is an int,
it defines the number of equal-width bins in the given range (10, by default). If bins is a sequence, it defines the bin edges, including the rightmost edge, allowing for non-uniform bin widths.
range ((float, float)): The lower and upper range of
the bins. If not provided, range contains all values in the table. Values outside the range are ignored.
density (bool): If False, the result will contain the number of
samples in each bin. If True, the result is the value of the probability density function at the bin, normalized such that the integral over the range is 1. Note that the sum of the histogram values will not be equal to 1 unless bins of unity width are chosen; it is not a probability mass function.
