Histogram¶

Histogram of a list of numeric samples.

$ wo 'Head[Histogram[{1, 2, 2, 3, 3, 3}]]'

A bin specification and a height specification may follow the data. {w} sets the bin width and "PDF" normalizes the bars to a probability density:

$ wo 'Head[Histogram[{1, 2, 2, 3, 3, 3}, {1}, "PDF"]]'
Graphics

Several datasets (a list of lists) are drawn as overlaid histograms:

$ wo 'Head[Histogram[{{1, 2, 2, 3}, {5, 6, 6, 7}}]]'
Graphics

Same options as BarChart, plus:

• Bins — Automatic, an integer (number of bins), a bin width {w}, or a list of bin edges {{e1, e2, ...}}.
• Height spec — "Count" (default), "PDF", "Probability", "CumulativeCount", or "CDF".
