#### Description:

This attribute controls the appearance of an annotated coordinate grid (drawn with the astGrid function) by determining whether a border is drawn around regions corresponding to the valid physical coordinates of a Plot (c.f. astBorder).

If the Border value of a Plot is non-zero, then this border will be drawn as part of the grid. Otherwise, the border is not drawn (although axis labels and tick marks will still appear, unless other relevant Plot attributes indicate that they should not). The default behaviour is to draw the border if tick marks and numerical labels will be drawn around the edges of the plotting area (see the Labelling attribute), but to omit it otherwise.

Type:

  Integer (boolean).

#### Applicability

All Plots have this attribute.
