Class LegendRenderAttributes

java.lang.Object
  com.davisor.graphics.RenderAttributes
      com.davisor.graphics.chart.LegendRenderAttributes

All Implemented Interfaces:

com.davisor.core.Dupable, java.io.Serializable

public class LegendRenderAttributes

extends RenderAttributes

LegendRenderAttributes represents chart legend rendering attributes. The attributes control in particular the following legend area aspects:

• legend background borderline width and stroke (backStroke)
• legend background borderline color (backColor)
• legend background fill paint (backPaint)
• legend text font typeface and size (labelFont)
• legend text color (labelColor)
• legend alignment in relation to chart (legendAlignment)

The legend background stroke and color attributes control a legend's outer borderline appearance. The stroke sets the borderline style and width, while the color attribute defines the paint used to draw the borderline. The background paint is used to fill the legend background area.

Label font and color define the style and color for the label texts.

Since:

JDK1.2

LegendRenderAttributes

public LegendRenderAttributes(java.awt.Paint color,
                              java.awt.Paint paint,
                              java.awt.Stroke stroke,
                              java.awt.Shape shape,

                              RenderAttributes defaults)

Creates a render attributes set with the given initial default attribute values. The values will be installed in slot zero, the default index is also set to zero and exceptions are disabled. The result is that the attribute set will behave as if it had an equal value initially set for each slot.

Parameters:

color - initial color attribute values (may be null)

paint - initial paint attribute values (may be null)

stroke - initial stroke attribute values (may be null)

shape - initial shape attribute values (may be null)

font - initial font attribute values (may be null)

alignment - initial alignment attribute values (may be null)

composite - initial composite attribute values (may be null)

defaults - default attribute values (may be null)
