Series

A set of data points

Each set of
related data points makes up one series. In the preceding
graph, there is a series for Stellar sales, another series
for Cosmic sales, and another series for Galactic sales.
Each series in a graph is distinguished by color, pattern,
or symbol.

Categories

The major divisions of the data

Series data are divided into categories, which are
often non-numeric. In the preceding graph, the series are
divided into four categories: Q1, Q2, Q3, and Q4. Categories
represent values of the independent
variable(s).

Values

The values for the data points (dependent
variables).
