| equals | | public boolean equals(Object obj)(Code) | | Tests this renderer for equality with an arbitrary object.
Parameters:
obj - the object (null permitted). A boolean. |
| getLegendItem | | public LegendItem getLegendItem(int datasetIndex, int series)(Code) | | Returns a default legend item for the specified series. Subclasses
should override this method to generate customised items.
Parameters:
datasetIndex - the dataset index (zero-based).
Parameters:
series - the series index (zero-based). A legend item for the series. |
| getPassCount | | public int getPassCount()(Code) | | Returns 2, the number of passes required by the renderer.
The
XYPlot will run through the dataset this number of times.
The number of passes required by the renderer. |
| initialise | | public XYItemRendererState initialise(Graphics2D g2, Rectangle2D dataArea, XYPlot plot, XYDataset data, PlotRenderingInfo info)(Code) | | Initialises the renderer and returns a state object that should be
passed to subsequent calls to the drawItem() method. This method will
be called before the first item is rendered, giving the renderer an
opportunity to initialise any state information it wants to maintain.
The renderer can do nothing if it chooses.
Parameters:
g2 - the graphics device.
Parameters:
dataArea - the area inside the axes.
Parameters:
plot - the plot.
Parameters:
data - the data.
Parameters:
info - an optional info collection object to return data back to the caller. A state object. |
| setRoundXCoordinates | | public void setRoundXCoordinates(boolean round)(Code) | | Sets the flag that controls whether or not the x-coordinates (in
Java2D space) are rounded to integer values, and sends a
RendererChangeEvent to all registered listeners.
Parameters:
round - the new flag value.
since:
1.0.4
