his·to·gram

(his'tō-gram),
1. A graphic columnar or bar representation to compare the magnitudes of frequencies or numbers of items.
2. Graphic representation of the frequency distribution of a variable, in which rectangles are drawn with their bases on a uniform linear scale representing intervals, and their heights are proportional to the values within each of the intervals.
