Graph IDEBasic Graphics ► Polygon

A polygon graphic is a sequence of points connected by line segments. When no line segments defined by the points intersect then the graphic is a polygon. If they intersect then the graphic is more general geometrically speaking. The figure below shows some examples of a polygon.

Some standard operations are itemized below.

Data Editor

The Data Editor for the Polygon is shown below.

Table

Table controls are described in the Tables section.

The rows represent vertex values. While in Atomic mode, the cell represents a point (x and y value) and while in component mode the cell represents either a x or y value. Hence, in atomic mode there is one column while in component mode there are two columns.

Common Controls

Controls common to all graphics are described in the Graphics section.

Point Editing

Editing Off/On : Places the graphic into or out of edit mode. While in edit mode the vertices are shown by indicators and can be adjusted using mouse or touch events. Double-clicking the graphic also toggles this edit mode.

Select/Move or Add/Delete : Select/Move mode permits the vertex editing to select and move the vertex location while Add/Delete mode will delete a vertex if it is hit or add a vertex if a polygon segment is hit. This can also be accomplished using the shift key if available.
