    a widget.

    Where counts are the bin values in the histogram
    and colormap is a tuple of (R, G, B) tuples the same length
    as counts. These are the colors to apply to the histogram bars.
    Colormap can also contain a single tuple (R, G, B), in which case this is
    the color applied to all bars of that histogram.

    The histogram assumes the bins were evenly spaced.
