Constructor Summary
XYStepRenderer()
Constructs a new renderer with no tooltip or URL generation.
XYStepRenderer(XYToolTipGenerator toolTipGenerator, XYURLGenerator urlGenerator)
Constructs a new renderer with the specified tool tip and URL generators.
Method Summary
Objectclone()
Returns a clone of the renderer.
voiddrawItem(Graphics2D g2, XYItemRendererState state, Rectangle2D dataArea, PlotRenderingInfo info, XYPlot plot, ValueAxis domainAxis, ValueAxis rangeAxis, XYDataset dataset, int series, int item, CrosshairState crosshairState, int pass)
Draws the visual representation of a single data item.

Constructor Detail

XYStepRenderer

public XYStepRenderer()
Constructs a new renderer with no tooltip or URL generation.

XYStepRenderer

public XYStepRenderer(XYToolTipGenerator toolTipGenerator, XYURLGenerator urlGenerator)

Parameters: toolTipGenerator the item label generator (null permitted). urlGenerator the URL generator (null permitted).

Method Detail

clone

public Object clone()
Returns a clone of the renderer.

Returns: A clone.

Throws: CloneNotSupportedException if the renderer cannot be cloned.

drawItem

public void drawItem(Graphics2D g2, XYItemRendererState state, Rectangle2D dataArea, PlotRenderingInfo info, XYPlot plot, ValueAxis domainAxis, ValueAxis rangeAxis, XYDataset dataset, int series, int item, CrosshairState crosshairState, int pass)
Draws the visual representation of a single data item.

Parameters: g2 the graphics device. state the renderer state. dataArea the area within which the data is being drawn. info collects information about the drawing. plot the plot (can be used to obtain standard color information etc). domainAxis the domain axis. rangeAxis the vertical axis. dataset the dataset. series the series index (zero-based). item the item index (zero-based). crosshairState crosshair information for the plot (null permitted). pass the pass index (ignored here).
