Table 26-2: Organization of a graph

Part of graph
|
What it is
|
|
Title
|
An optional title for the graph. The
title appears at the top of the graph.
|
|
Value axis
|
The axis of the graph along which the
values of the dependent variable(s) are plotted. In a column graph,
as shown in the preceding graph, the Value axis corresponds to the
y axis in an XY presentation. In other types of graphs, such as
a bar graph, the Value axis can be along the x dimension.
|
|
Category axis
|
The axis along which are plotted the
major divisions of the data, representing the independent variable(s).
In the preceding graph, the Category axis corresponds to the x axis.
It plots four categories: Q1, Q2, Q3, and Q4. These form the major
divisions of data in the graph.
|
|
Series
|
A set of data points. There are three
series in the preceding graph: Stellar, Cosmic, and Galactic. In
bar and column charts, each series is represented by bars or columns
of one color or pattern.
|
|
Series axis
|
The axis along which the series are plotted
in three-dimensional (3D) graphs.
|
|
Legend
|
An optional listing of the series. The
preceding graph contains a legend that shows how each series is
represented in the graph.
