### Edge(axis)

Which edges to label in a Plot

#### Description:

This attribute controls the appearance of an annotated coordinate grid (drawn with the astGrid function) by determining which edges of a Plot are used for displaying numerical and descriptive axis labels. It takes a separate value for each physical axis of the Plot so that, for instance, the setting " Edge(2)=left" specifies which edge to use to display labels for the second axis.

The values " left" , " top" , " right" and " bottom" (or any abbreviation) can be supplied for this attribute. The default is usually " bottom" for the first axis and " left" for the second axis. However, if exterior labelling was requested (see the Labelling attribute) but cannot be produced using these default Edge values, then the default values will be swapped if this enables exterior labelling to be produced.

Type:
String.

#### Applicability

##### Plot
All Plots have this attribute.
##### Plot3D
The Plot3D class ignores this attributes. Instead it uses its own RootCorner attribute to determine which edges of the 3D plot to label.

#### Notes:

• In some circumstances, numerical labels will be drawn along internal grid lines instead of at the edges of the plotting area (see the Labelling attribute). In this case, the Edge attribute only affects the placement of the descriptive labels (these are drawn at the edges of the plotting area, rather than along the axis lines).
