Individual attributes

Graphic attributes are optional arguments of the form display=value, they must be given as last argument of a graphic instruction. Attributes are ordered in several categories: color, point shape, point width, line style, line thickness, legend value, position and presence. In addition, surfaces may be filled or not, 3-d surfaces may be filled with a texture, 3-d objects may also have properties with respect to the light. Attributes of different categories may be added, e.g.
