Method Summary | |
---|---|
Object | clone()
Returns a clone of the renderer.
|
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.
|
boolean | equals(Object obj)
Tests this renderer for equality with an arbitrary object.
|
double | getStepPoint()
Returns the fraction of the domain position between two points on which
the step is drawn. |
int | hashCode()
Returns a hash code for this instance.
|
void | setStepPoint(double stepPoint)
Sets the step point and sends a RendererChangeEvent to all
registered listeners.
|
Parameters: toolTipGenerator the item label generator (null
permitted). urlGenerator the URL generator (null
permitted).
Returns: A clone.
Throws: CloneNotSupportedException if the renderer cannot be cloned.
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.
Parameters: obj the object (null
permitted).
Returns: A boolean.
Returns: The fraction of the domain position between two points where the step is drawn.
Since: 1.0.10
Returns: A hash code.
Parameters: stepPoint the step point (in the range 0.0 to 1.0)
Since: 1.0.10
