Icon Description
This graphic is described in surrounding text.
Aggregations - the mathematical functions to aggregate data. For text items (e.g. Region), the typical aggregations are Count, Max, and Min. For example, you can count the number of Regions items, or find the highest or lowest (where A might be the highest and Z the lowest).

For numeric items, typical aggregations are Sum, Count, Max, Min, Average, and Detail. For example, you can find the Sum or Average of the numeric data. The default aggregation (specified by the Discoverer manager) is displayed in bold.

This graphic is described in surrounding text.
Business area - displays a business area created by the Discoverer manager. To select another business area for the new worksheet, click the drop-down arrow and choose from the list of business areas. A business area contains one or more folders.
This graphic is described in surrounding text.
Calculation - a mathematical expression to produce new data from other items.

Note: Calculations defined by the Discoverer manager appear in folders. User-defined calculations do not appear in folders.

This graphic is described in surrounding text.
Condition - a filter for finding specific data.

Note: Conditions defined by the Discoverer manager appear in folders. User-defined conditions do not appear in folders.

This graphic is described in surrounding text.
Folder - contains the items that you can include in your worksheets. Click the plus (+) and minus (-) symbol next to the folder to open and close the folder.
This graphic is described in surrounding text.
Item - corresponds to a column on a table or a level on a crosstab axis. Axis items remain constant and have relatively few unique values (e.g. the names of departments in your organization, the names of your Sales Regions). The values of an axis item are shown as a list of values (LOV).
This graphic is described in surrounding text.
Item Value - an item in a list of values (LOV).
This graphic is described in surrounding text.
Numeric Item - represents numeric data. The values of numeric items can change as you analyze the data (e.g. summing profits will produce different results for cities than for regions). Numeric items behave as axis items on table worksheets and correspond to the data in the body of a crosstab.
This graphic is described in surrounding text.
Percentage - a percentage that Discoverer calculates to summarize values in a numeric worksheet item.
This graphic is described in surrounding text.
Tick symbol (or check mark) - worksheet items marked with a tick symbol are currently displayed on the current worksheet.

Note: Items that are grayed out are not available to the worksheet.

What are axis items?

Axis items are items that appear in the workbook window in:

Typically, axis items have a relatively few discrete values. You use axis items to identify particular data values.

For example, if a crosstab worksheet shows sales figures, it might include Year as the top axis and Region as the left axis. You can then use the axis items to see the sales of a particular region in a particular year. In the figure below, Department item is on the page axis, Year is on the top axis, and Region is on the left axis.
