Attributes and Styles
The look of each basic graphics primitives can be changed using the four attributes classes:
TAttFill, TAttLine,
TAttMarker and
TAttText.
The classes which need one of the attributes simple derives from them. In that case the attributes are set to a given object. There is also a global way to set attributes using
TStyle allows to change high level attributes in a global way, not related to a specific object.
