The Area form (
)
is available from the
Area layer control,
and outlines or fills areas that are defined in a table row.
Example Area plot
Area form configuration panel
Configuration options are:
-
Shading Mode
- See Appendix A.4.6.
-
Polygon Mode
- Defines how the polygon is drawn. Options are
-
outline:
draws a line round the outside of the polygon
-
fill:
fills the interior of the polygon
-
cross:
draws a line round the outside of the polygon
and lines between all the vertices
-
Thickness
- Controls the line thickness used when drawing polygons.
Zero, the default value, means a 1-pixel-wide line is used.
Larger values make drawn lines thicker, but note changing
this value will not affect all shapes, for instance filled
polygons contain no line drawings.
-
Minimal Size
- Defines a threshold size in pixels below which,
instead of the shape defined by the Area coordinate,
a replacement marker will be painted instead.
If this is set to zero, then only the shape itself
will be plotted, which may mean it appears as only a single pixel.
By setting a larger value, you can ensure that
the position of even small areas is easily visible,
at the expense of giving them an artificial shape and size.
This value also defines the size of the replacement markers.
-
Minimal Shape
- Selects the shape of replacement markers that get plotted
instead of very small areas, as controlled by the
Minimal Size setting.
