Bookshelf v7.5.3: Axis Terminology

Specialized terminology is used for axes in Siebel Tools and Siebel applications. Each axis has a special name, as shown in Table 47.

Table 47. Axis Terminology
Axis	Name	Meaning in Bar Charts	Meaning in Line Charts	Meaning in Pie Charts
X axis	Category	The horizontal axis (except in horizontal bar charts, in which the X axis is vertical along the left).	The horizontal axis.	The set of pie slice labels.
Y axis	Data Values	The vertical axis (except in horizontal bar charts, in which the Y axis is horizontal along the bottom).	The vertical axis.	The percentage of the circle occupied by each pie slice, and the corresponding numeric value.
Z axis	Series	A set of labels in the legend. In the stacked bar or cluster bar charts, each series label corresponds to a bar segment or bar of a particular color appearing in each stack or cluster.	A set of labels in the legend. In line charts, each series label in the legend corresponds to one curve.	Do not use a series field with pie charts, because only the first entry in each series will be charted.

An example of a chart with all three axes is the Project Revenue Analysis chart shown in Figure 192.

In this chart, the amount of revenue is plotted on the Y (data values) axis, quarters appear on the X (category) axis, and each bar color (Z, or series, axis) identifies a a different project.

NOTE: In charts with two Y axes, the first Y axis refers to the vertical axis on the left side, while the second Y axis refers to the one on the right side.
