public XYStepRenderer(XYToolTipGenerator toolTipGenerator, XYURLGenerator urlGenerator)
Constructs a new renderer with the specified tool tip and URL generators.
- Parameters:
toolTipGenerator
- the item label generator (null
permitted).urlGenerator
- the URL generator (null
permitted).
public Object clone() throws CloneNotSupportedException
Returns a clone of the renderer.
- Overrides:
- clone in interface XYLineAndShapeRenderer
- Returns:
- A clone.
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.
- Specified by:
- drawItem in interface XYItemRenderer
- Overrides:
- drawItem in interface XYLineAndShapeRenderer
- 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).
public boolean equals(Object obj)
Tests this renderer for equality with an arbitrary object.
- Overrides:
- equals in interface XYLineAndShapeRenderer
- Parameters:
obj
- the object (null
permitted).
- Returns:
- A boolean.
public double getStepPoint()
Returns the fraction of the domain position between two points on which the step is drawn. The default is 1.0d, which means the step is drawn at the domain position of the second`point. If the stepPoint is 0.5d the step is drawn at half between the two points.
- Returns:
- The fraction of the domain position between two points where the step is drawn.
- Since:
- 1.0.10
- See Also:
setStepPoint(double)
public int hashCode()
Returns a hash code for this instance.
- Overrides:
- hashCode in interface AbstractRenderer
- Returns:
- A hash code.
public void setStepPoint(double stepPoint)
Sets the step point and sends aRendererChangeEvent
to all registered listeners.
- Parameters:
stepPoint
- the step point (in the range 0.0 to 1.0)
- Since:
- 1.0.10
- See Also:
