# The "histograms" style automates the construction of barcharts with
# various stacking and clustering options.  But it doesn't offer much
# choice for coloring.
# This demo show using the "with boxes" plot style to generate clustered
# histograms with individual box coloring generated by a user-provided function.
# This could, for example, depend on data from other columns in the input.
