Below is a glossary of words used in this manual.
Additional definitions, and descriptions, are available in the online Graph Builder manual. Graph Builder is a more powerful tool that constructs tasks representations through a more comprehensive user interface.
| Terminology | Definition |
| Column | A Column refers to a column of a table (in the vertical direction) or a bar of a bar chart oriented in the y-direction. This dual meaning leads to a bit of confusing use of the word column in the Set Of Scalars task. |
| Page | A Page (aka: View, Screen) is what is shown as you use the standard navigation buttons. Generally a Page is thought of as a screen of information. Graph's pages traverse from Home > Task > Representation pages, and back, as shown in the Main Idea section. |
| Representation | All Tasks are comprised of rows which when touched navigate to a representation. A representation is either numeric (a bunch of numbers) or graphical (a graph). The number representation is used to show, retrieve and edit numeric data and the graphical representations are used to show that data. The Main Idea section diagrams the navigation to a representation as a final result of the navigation. |
| Scalar | A scalar is a single number such as 3.1415. A scalar can also be called a number which is more common but in this manual the word scalar is preferred. (Note: Technically, the use of the word "number" leads to ambiguity so scalar is desired.) |
| Tasks | Tasks are specific class of problems that are associated with a class of data. For example: A hypothetical line graph task operates on 2D points and that is why a line graph task is actually called "Set Of 2D Points Task" because the data is what binds the different representations of that task together (line, scatter, area, etc.). |
| Tool | Tools operate upon tasks and are represented by their own Page. |
| 2D Point | A 2D point is a pair of scalars, that is an ordered pair. The x-dimension is first and the y-dimension is second. The Set Of 2D Points task operates on 2D points. |
| 3D Point | A 3D point is a triplet of scalars, that is an ordered triplet. The x-dimension is first, y-dimension second and z-dimension is third. The 3D Points task operates on 3D points. |
