Method Detail

getRenderer

public static CartesianRenderer getRenderer(CartesianGraph cg,
                                            SGTData dmo,
                                            Attribute attr)

Factory method to create a new Renderer instance given the SGTData object and Attribute. For example, a LineCartesianRenderer is created if SGTData object is a SGTLine.

A renderer is constucted based on the two arguements.

SGTData	Attribute	CartesianRenderer
SGTPoint	PointAttribute	PointCartesianRenderer
SGTLine	LineAttribute	LineCartesianRenderer
SGTGrid	GridAttribute	GridCartesianRenderer
SGTVector	VectorAttribute	VectorCartesianRenderer
Collection	PointAttribute	PointCartesianRenderer
Collection	LineAttribute	LineCartesianRenderer
Collection	VectorAttribute	VectorCartesianRenderer
Annotation	n/a	AnnotationCartesianRenderer

Parameters:

dmo - DataModel object

draw

public abstract void draw(org.freehep.graphics2d.VectorGraphics g)

Render the SGTData object. This method should never be called directly.
