Box Chart

Box Plot (or Box Chart) is a convenient way of graphically depicting groups of numerical data through their quartiles. It provides a visual representation of statistical data based on the minimum, first quartile, median, third quartile, and maximum. Outliers can be plotted on Box Plots as individual points.

The term "box plot" comes from the fact that such a graph looks like a rectangle with lines extending from the top and bottom. Because of the extending lines, this chart type is sometimes called a Box-and-Whisker Plot (Box-and-Whisker Chart).

The distances between different box parts represent the degree of data dispersion and data asymmetry to identify outliers. It is possible to compare point values between themselves (in a single-series Box Plot) and also analyze the differences between values inside the categories (in multi-series Box Plots). In case of several series, points are grouped by category.
