Normally, histograms are generated with the 'smooth frequency' gnuplot style.
C<--histstyle> can be used to select different C<smooth> settings (see the
gnuplot C<help smooth> page for more info). Allowed values are 'frequency' (the
default), 'unique', 'cumulative' and 'cnormal'. 'unique' indicates whether a bin
has at least one item in it: instead of counting the items, it'll always report
0 or 1. 'cumulative' is the integral of the 'frequency' histogram. 'cnormal' is
like 'cumulative', but rescaled to end up at 1.0. Note that there's no
normalized 'frequency' option because gnuplot does not provide one.

bin has at least one item in it: instead of counting the items, it'll always
report 0 or 1. 'cumulative' is the integral of the 'frequency' histogram.
'cnormal' is like 'cumulative', but rescaled to end up at 1.0.
