Interface SymbolFactory
- All Known Implementing Classes:
- AbstractSymbolFactory, ErrorBarFactory
- public interface SymbolFactory
Interface of a symbol factory. A symbol is a GraphicalElement
or GraphicalComposite
. A symbol factory creates
the same type of symbols. In general, they have all the same size.
But they are distinguished from each other by their positions.
In addition they may also differ in other properties which will
be determined by Hints
.

createSymbol
public Symbol createSymbol(GraphPoint point,
Hint hintFromPreviousPoint,
Hint hintFromPreviousCurve)
- Creates a symbol for the specified point taking into account
the specified hints.
- Parameters:
point
- The position of the symbol. In general it is a transformation
of a corresponding DataPoint
into a
GraphPoint
.hintFromPreviousPoint
- Hint from the previous point of the same
Curve
or null.hintFromPreviousCurve
- Hint from the previous
Curve
or null.
createLegendSymbol
public GraphicalElement createLegendSymbol(GraphPoint centerPosition,
double size)
- Creates a symbol for the legend at the specified position.
- Parameters:
centerPosition
- Center position of the symbol.size
- The size of the symbol. Will not be used if the symbol
of the curve points have all the same size. In this case
the symbol for the legend has the size of the curve symbols.
