public Legend(ConfigParameters config)

Creates an instance from the specified configuration parameters. All numbers (lengths, fontsizes, linethicknesses, etc.) are in device-independent units.

Key & Default Value	Type	Mandatory	Description
bottomDistance = 0.02	double	no	Distance between the last row and the bottom of the legend box.
boxAttributes = default values of ShapeAttributes with a white fill color.	ConfigParameters	no	Attributes of the legend box.
boxHeight = 0.1	double	no	Height of the legend box.
boxWidth = 0.2	double	no	Width of the legend box.
curveTitleAttributes = default values of BasicGraphicAttributes	ConfigParameters	no	Text attributes of curve titles printed in the legend.
curveTitleDistance = 0.005	double	no	Horizontal distance between the line part of the legend symbol and the curve title.
leftDistance = 0.01	double	no	Horizontal distance between the line part of the legend symbol and the left border of the legend box.
lineLength = 0.035	double	no	Length of the line part of the legend symbol.
symbolSize = 0.01	double	no	Size of the symbol part of the legend symbol. Will be the size argument of createLegendSymbol in a SymbolFactory.
titleAttributes = default values of BasicGraphicAttributes with a text anchor CENTER TOP.	ConfigParameters	no	Text attributes of the title of the legend box.
title = Legend	String	no	Title of the legend box.
titleDistance = 0.005	double	no	Distance between the center of the upper line of the legend box and the anchor of the legend title.
