How to use the xhistogram.core.histogram function in xhistogram

args_data = [a.data for a in args_transposed]

    if N_weights:
        weights_data = args_data.pop()
    else:
        weights_data = None

    if dim is not None:
        dims_to_keep = [d for d in all_dims_ordered if d not in dim]
        axis = [args_transposed[0].get_axis_num(d) for d in dim]
    else:
        dims_to_keep = []
        axis = None

    print(args_data[0].shape)
    h_data = _histogram(*args_data, weights=weights_data, bins=bins, axis=axis,
                        block_size=block_size)

    # create output dims
    new_dims = [a.name + bin_dim_suffix for a in args[:N_args]]
    output_dims = dims_to_keep + new_dims

    # create new coords
    bin_centers = [0.5*(bin[:-1] + bin[1:]) for bin in bins]
    new_coords = {name: ((name,), bin_center, a.attrs)
                  for name, bin_center, a in zip(new_dims, bin_centers, args)}

    old_coords = {name: a0[name]
                  for name in dims_to_keep if name in a0.coords}
    all_coords = {}
    all_coords.update(old_coords)
    all_coords.update(new_coords)
