Pivot charts are most easily expressed with a column chart, also called a bar graph.
The main focus of a pivot chart is to process incoming data and give an “at-a-glance” representation of that data. A bar graph displays these values in such a manner.
A “pivot chart” is a common term used to describe such a collection of data, however that specific term is owned by Microsoft. It is comprised of data found on a pivot table. Microsoft Excel has built-in features designed to manipulate such data.
