Also known as a Range Bar/Column Graph, Floating Bar Graph, Difference Graph, High-Low Graph.
A chart used to display dataset ranges between a minimum value and a maximum value. Span Charts are ideal for comparing ranges, typically for categorised ranges.
Span Charts focus the reader on only the extreme values and give no information on the values in between the minimum and maximum values or on averages or data distribution.
