public class IlvRendererLegendItem
extends IlvLegendItem

A class defining a legend item linked to a chart renderer. This class allows to have legend items with a graphical representation of their symbol matching the ones used by their associated renderers. When an IlvRendererLegendItem is drawn, its paint() method calls the IlvChartRenderer.drawLegendSymbol(ilog.views.chart.IlvLegendItem, java.awt.Graphics, int, int, int, int) method to draw the symbol according to the current rendering settings of the chart renderer, and calls the IlvChartRenderer.getLegendText(ilog.views.chart.IlvLegendItem) method to draw the label. Instances of this class are automatically created by a renderer when it is added to a chart.

JViews 5.0

Constructor Detail

IlvRendererLegendItem

public IlvRendererLegendItem(IlvChartRenderer disp)

Creates a new IlvRendererLegendItem associated with the given renderer. The label of this item is initialized when the item is added to the legend with the string returned by IlvChartRenderer.getLegendText().

Method Detail

getRenderer

public final IlvChartRenderer getRenderer()

Returns the chart renderer attached to this item.

updateLabel

protected void updateLabel()

Updates the label before drawing this item. The default implementation fetches the value from the renderer.

Since:

JViews 8.1

paintComponent

protected void paintComponent(Graphics g)

Draws this item.

Overrides:

paintComponent in class IlvLegendItem

drawSymbol

public void drawSymbol(Graphics g,
                       Rectangle symbolBounds)

Draws the symbol part of this item.

This implementation clips the graphics context to the symbol bounds and calls IlvChartRenderer.drawLegendSymbol(ilog.views.chart.IlvLegendItem, java.awt.Graphics, int, int, int, int) to render the symbol.

Overrides:

drawSymbol in class IlvLegendItem

Since:

JViews 8.1
