Data Graphics > Function

A function is a sequence of points connected by lines. The x-values of the points increase as the sequence index increases. A function is very similar to a Polygon (see Polygon). The figures below show examples of the use of functions.

Standard Operations

To create a function bring forward the Graphic Selector, click the function factory cell and then mouse down on a Graphic View and drag the cursor to another point. The initial and final cursor locations define the boundary of a predefined function graphic.

Resizing the function transforms all points simultaneously. A function cannot be rotated because it has to maintain its function properties. For more information on editing a function, including point-wise editing, see Standard Editing.

The normal way to modify the points of a function is through the function's Inspector Editor's data entry field. That field accepts a whitespace sequence of x y pairs.

For information on entering data points see Export And Import Data: Raw Data Points.

Inspector Editor

The Inspector Editor for the function is shown below.
