Polygon()

Displays a polygon on the graphics device

POLYGON/DRAW [/FILLED] [/OUTLINE] xarray=RealArray yarray=RealArray [colour=Colour] [line_thickness=Real] Draws a polygon onto a graphics device.
POLYGON/ALTER [/FILLED] [/OUTLINE] [xarray=RealArray] [yarray=RealArray] [colour=Colour] [line_thickness=Real] object=Gobject Alters a polygon on a graphics device

example:

	# Draws a polygon plot with crosses 
	# then alters the marker symbol.
	>> Polygon/draw x_points y_points
	>> Markers/alter line_thickness=10.0 object=obj(0,0,0)

Note: By default the polygon is outlined.

Polygon/Draw

Draws a polygon onto a graphics device

Parameters:

/Filled

Colours the whole of the polygon.

/Outline

Colours the perimeter of the polygon.

Xarray (RealArray)

Specifies the x co-ordinates of the polygon.

Yarray (RealArray)

Specifies the y co-ordinates of the polygon.

Colour (Colour)

Sets the colour of the polygon.

Line_thickness (Real)

Sets the line thickness of the polygon.

RESULT = (Polygon)

Returns all of the properties of the newly created polygon.

Polygon/Alter

Parameters:

/Filled

Colours the whole of the polygon.

/Outline

Colours the perimeter of the polygon.

Xarray (RealArray)

Not Yet Implemented. Specifies the x co-ordinates of the polygon.

Yarray (RealArray)

Not Yet Implemented. Specifies the y co-ordinates of the polygon.

Colour (Colour)

Sets the colour of the polygon.

Line_thickness (Real)

Sets the line thickness of the polygon.

Object (Gobject)
