Understanding Chart Class Terms

The following is a list of Chart class terms and their descriptions:

Field or Control	Description
Label	Text that identifies the data on one of the axes.
Legend	Text that identifies the different series in the chart.
Series	A grouping of related information. For example, if you were tracking sales for several divisions over many years, each division could be a series. Generally, every series in a chart has a distinct color. You can have more than one series in a chart for comparison. Each line in a line chart represents one series.
Title	The three titles are main, x-axis, and y-axis. Each title identifies a portion of the chart.
Subtitle	The subtitle appears to the left of the main title.
Footnote	The footnote appears at the bottom left of the chart.
X-axis	The axis that data is measured against.
Y-axis	The axis that contains the data. In most charts, this is the vertical axis. In a horizontal bar chart, this is the horizontal axis.
Secondary y-axis	A secondary y-axis (or Y2 axis) is one that contains data that differs from the primary y-axis but is measured against the same x-axis data and plotted on the same chart as the primary y-axis data.
Reference area	A reference area is displayed in conjunction with a chart as a band of color drawn based on numeric values along a chart axis. For each band of color, you would create a separate instance of the ReferenceArea class.
Reference line	A reference line is displayed in conjunction with a chart as a colored line drawn based on a numeric value along a chart axis. For each line, you would create a separate instance of the ReferenceLine class
Series	A series is a set of data grouped together based on a common attribute and most often is plotted on the y-axis. In PeopleSoft applications, chart data series are a grouping of related information. For example, if you were tracking sales for several divisions over many years, each division could represent a series. Generally, every series in a chart has a distinct color and you can have more than one series in a chart for comparison..
Tooltip	A tooltip is a message that appears when the cursor is positioned over a data point, legend or other element in a chart. The tooltip provides more information about the item of interest. While default tooltips are generated automatically, the ToolTipLabel class and the SetDataHints method provide two alternative methodologies for generating custom tooltips.
