| XYBarRenderer | | public XYBarRenderer()(Code) | | The default constructor.
|
| XYBarRenderer | | public XYBarRenderer(double margin)(Code) | | Constructs a new renderer.
Parameters:
margin - the percentage amount to trim from the width of each bar. |
| 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)(Code) | | Draws the visual representation of a single data item.
Parameters:
g2 - the graphics device.
Parameters:
state - the renderer state.
Parameters:
dataArea - the area within which the plot is being drawn.
Parameters:
info - collects information about the drawing.
Parameters:
plot - the plot (can be used to obtain standard color information etc).
Parameters:
domainAxis - the domain axis.
Parameters:
rangeAxis - the range axis.
Parameters:
dataset - the dataset.
Parameters:
series - the series index (zero-based).
Parameters:
item - the item index (zero-based).
Parameters:
crosshairState - crosshair information for the plot (null permitted).
Parameters:
pass - the pass index. |
| drawItemLabel | | protected void drawItemLabel(Graphics2D g2, XYDataset dataset, int series, int item, XYPlot plot, XYItemLabelGenerator generator, Rectangle2D bar, boolean negative)(Code) | | Draws an item label. This method is overridden so that the bar can be
used to calculate the label anchor point.
Parameters:
g2 - the graphics device.
Parameters:
dataset - the dataset.
Parameters:
series - the series index.
Parameters:
item - the item index.
Parameters:
plot - the plot.
Parameters:
generator - the label generator.
Parameters:
bar - the bar.
Parameters:
negative - a flag indicating a negative value. |
| equals | | public boolean equals(Object obj)(Code) | | Tests this renderer for equality with an arbitrary object.
Parameters:
obj - the object to test against (null permitted). A boolean. |
| findDomainBounds | | public Range findDomainBounds(XYDataset dataset)(Code) | | Returns the lower and upper bounds (range) of the x-values in the
specified dataset. Since this renderer uses the x-interval in the
dataset, this is taken into account for the range.
Parameters:
dataset - the dataset (null permitted). The range (null if the dataset is null or empty). |
| 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. |
| getUseYInterval | | public boolean getUseYInterval()(Code) | | Returns a flag that determines whether the y-interval from the dataset is
used to calculate the length of each bar.
A boolean.
See Also: XYBarRenderer.setUseYInterval(boolean) |
| initialise | | public XYItemRendererState initialise(Graphics2D g2, Rectangle2D dataArea, XYPlot plot, XYDataset dataset, PlotRenderingInfo info)(Code) | | Initialises the renderer and returns a state object that should be
passed to all subsequent calls to the drawItem() method. Here we
calculate the Java2D y-coordinate for zero, since all the bars have
their bases fixed at zero.
Parameters:
g2 - the graphics device.
Parameters:
dataArea - the area inside the axes.
Parameters:
plot - the plot.
Parameters:
dataset - the data.
Parameters:
info - an optional info collection object to return data back to the caller. A state object. |
| setUseYInterval | | public void setUseYInterval(boolean use)(Code) | | Sets the flag that determines whether the y-interval from the dataset is
used to calculate the length of each bar, and sends a
RendererChangeEvent to all registered listeners.
Parameters:
use - the flag.
