1.1 Glossary

This document uses the following terms:

3-D Phong shading: A shading algorithm that is used to apply shading to 3-D charts. The algorithm interpolates color between points on the surface of a chart to give a smooth 3-D appearance.

active cell: The cell that is currently selected in a worksheet.

active selection: The current selection of cells, rows, or columns that includes the active cell in a datasheet.

anchor: A set of qualifiers and quantifiers that specifies the location of an element or object within a document. These values are typically relative to another element or known location in the document, such as the edge of a page or margin.

Augmented Backus-Naur Form (ABNF): A modified version of Backus-Naur Form (BNF), commonly used by Internet specifications. ABNF notation balances compactness and simplicity with reasonable representational power. ABNF differs from standard BNF in its definitions and uses of naming rules, repetition, alternatives, order-independence, and value ranges. For more information, see [RFC5234].

background color: A color against which characters, patterns, and graphics are displayed. See also foreground color.

beta: A pre-released version of a product that is sent to customers and partners for evaluation and feedback.

down bar: See up-down bar.

drawing object: A shape, curve, line, WordArt, or other type of graphical object that can be inserted into a document.

drop lines: A set of supplemental lines on an area chart or a line chart. Drop lines increase the legibility of a chart by connecting each data point in a series to the category axis.

fill pattern: A repetitive design that users can add to the background of a cell, shape, or chart element.

floating-point number: A number that is represented by a mantissa and an exponent according to a given base. The mantissa is typically a value between "0" and "1". To find the value of a floating-point number, the base is raised to the power of the exponent, and the mantissa is multiplied by the result.

floor: An extension of the horizontal axis, or the area created by the inclusion of the z axis, in a 3-D chart to create a three-dimensional effect. See also wall.

font: An object that defines the graphic design, or formatting, of a collection of numbers, symbols, and letters. A font specifies the style (such as bold and strikeout), size, family (a typeface such as Times New Roman), and other qualities to describe how the collection is drawn.

font scaling: A process of resizing a proportionally-spaced font.

forecast: The process of projecting values forward or backward in a series, based on trends in existing data.

foreground color: A color that is used to display text, patterns, and other objects that appear in front of or on top of the background color.

format string: A string that contains the number formatting information to apply to data, such as decimal position, percentage indicator, or currency symbol.

formatting run: A set of formatting properties that are applied to a text run.

formula: A logical equation or function that produces a result in a spreadsheet application.

graph object: An object that represents a chart and the datasheet that contains the data for that chart.

horizontal alignment: A formatting setting that specifies how content is positioned within the horizontal space of a cell, object, or page. Content can be aligned along the left or right edge, or distributed evenly across the horizontal space.

justify distributed: A special, distributed-alignment setting that evenly distributes the last line of text in a cell. The setting is primarily used for East Asian languages. See also distributed alignment.

leader line: A line that connects a data label to its corresponding data point. The primary purpose of a leader line is to increase legibility.
