public static final int AREA
Useful constant for specifying the type of rendering (area only).
- Field Value:
- 2
public static final int AREA_AND_SHAPES
Useful constant for specifying the type of rendering (area and shapes).
- Field Value:
- 3
public static final int SHAPES
Useful constant for specifying the type of rendering (shapes only).
- Field Value:
- 1
public XYStepAreaRenderer(int type)
Constructs a new renderer.
- Parameters:
type
- the type of the renderer.
public XYStepAreaRenderer(int type, XYToolTipGenerator toolTipGenerator, XYURLGenerator urlGenerator)
Constructs a new renderer. To specify the type of renderer, use one of the constants: AREA, SHAPES or AREA_AND_SHAPES.
- Parameters:
type
- the type of renderer.toolTipGenerator
- the tool tip generator to use (null
permitted).urlGenerator
- the URL generator (null
permitted).
public Object clone() throws CloneNotSupportedException
Returns a clone of the renderer.
- Overrides:
- clone in interface AbstractXYItemRenderer
- 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
- 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 range 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.
public boolean equals(Object obj)
Tests this renderer for equality with an arbitrary object.
- Overrides:
- equals in interface AbstractXYItemRenderer
- Parameters:
obj
- the object (null
permitted).
- Returns:
- A boolean.
public boolean getPlotArea()
Returns true if Area is being plotted by the renderer.
- Returns:
true
if Area is being plotted by the renderer.
- See Also:
setPlotArea(boolean)
public double getRangeBase()
Returns the value on the range axis which defines the 'lower' border of the area.
- Returns:
double
the value on the range axis which defines the 'lower' border of the area.
- See Also:
setRangeBase(double)
public boolean getShapesVisible()
Returns true if shapes are being plotted by the renderer.
- Returns:
true
if shapes are being plotted by the renderer.
- See Also:
setShapesVisible(boolean)
public XYItemRendererState initialise(Graphics2D g2, Rectangle2D dataArea, XYPlot plot, XYDataset data, PlotRenderingInfo info)
Initialises the renderer. Here we calculate the Java2D y-coordinate for zero, since all the bars have their bases fixed at zero.
- Specified by:
- initialise in interface XYItemRenderer
- Overrides:
- initialise in interface AbstractXYItemRenderer
- Parameters:
g2
- the graphics device.dataArea
- the area inside the axes.plot
- the plot.data
- the data.info
- an optional info collection object to return data back to the caller.
- Returns:
- The number of passes required by the renderer.
public boolean isOutline()
Returns a flag that controls whether or not outlines of the areas are drawn.
- Returns:
- The flag.
- See Also:
setOutline(boolean)
public boolean isShapesFilled()
Returns the flag that controls whether or not the shapes are filled.
- Returns:
- A boolean.
- See Also:
setShapesFilled(boolean)
protected static double restrictValueToDataArea(double value, XYPlot plot, Rectangle2D dataArea)
Helper method which returns a value if it lies inside the visible dataArea and otherwise the corresponding coordinate on the border of the dataArea. The PlotOrientation is taken into account. Useful to avoid possible sun.dc.pr.PRException: endPath: bad path which occurs when trying to draw lines/shapes which in large part lie outside of the visible dataArea.
- Parameters:
value
- the value which shall beplot
- the plot (can be used to obtain standard color information etc).dataArea
- the area within which the data is being drawn.
- Returns:
double
value inside the data area.
public void setOutline(boolean show)
Sets a flag that controls whether or not outlines of the areas are drawn, and sends aRendererChangeEvent
to all registered listeners.
- Parameters:
show
- the flag.
- See Also:
isOutline()
public void setPlotArea(boolean flag)
Sets a flag that controls whether or not areas are drawn for each data item and sends aRendererChangeEvent
to all registered listeners.
- Parameters:
flag
- the flag.
- See Also:
getPlotArea()
public void setRangeBase(double val)
Sets the value on the range axis which defines the default border of the area, and sends aRendererChangeEvent
to all registered listeners. E.g. setRangeBase(Double.NEGATIVE_INFINITY) lets areas always reach the lower border of the plotArea.
- Parameters:
val
- the value on the range axis which defines the default border of the area.
- See Also:
getRangeBase()
public void setShapesFilled(boolean filled)
Sets the 'shapes filled' for ALL series and sends aRendererChangeEvent
to all registered listeners.
- Parameters:
filled
- the flag.
- See Also:
isShapesFilled()
public void setShapesVisible(boolean flag)
Sets the flag that controls whether or not shapes are displayed for each data item, and sends aRendererChangeEvent
to all registered listeners.
- Parameters:
flag
- the flag.
- See Also:
getShapesVisible()
