Constructor Detail

XYStepRenderer

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


XYStepRenderer

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).
Method Detail

getStepPoint

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)

setStepPoint

public void setStepPoint(double stepPoint)
Sets the step point and sends a RendererChangeEvent to all registered listeners.

Parameters:
stepPoint - the step point (in the range 0.0 to 1.0)
Since:
1.0.10

getStepPoint()

drawItem

public void drawItem(java.awt.Graphics2D g2,
                     XYItemRendererState state,

                     PlotRenderingInfo info,
                     XYPlot plot,
                     ValueAxis domainAxis,
                     ValueAxis rangeAxis,
                     XYDataset dataset,
                     int series,
                     int item,
                     CrosshairState crosshairState,

Draws the visual representation of a single data item.

Specified by:
drawItem in interface XYItemRenderer
Overrides:
drawItem in class 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.

equals

public boolean equals(java.lang.Object obj)
Tests this renderer for equality with an arbitrary object.

Overrides:
equals in class XYLineAndShapeRenderer
Parameters:
obj - the object (null permitted).
Returns:
A boolean.

hashCode

public int hashCode()
Returns a hash code for this instance.

Overrides:
hashCode in class AbstractRenderer
Returns:
A hash code.

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException
Returns a clone of the renderer.
