coordinate on the border of the dataArea. | | public void | setOutline(boolean show)

Parameters:
type - the type of renderer.
Parameters:
toolTipGenerator - the tool tip generator to use (null permitted).
Parameters:
urlGenerator - the URL generator (null permitted). |
| 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 data 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. |
| equals | | public boolean equals(Object obj)(Code) | | Tests this renderer for equality with an arbitrary object.
Parameters:
obj - the object (null permitted). A boolean. |
| getRangeBase | | public double getRangeBase()(Code) | | Returns the value on the range axis which defines the 'lower' border of
the area.
double the value on the range axis which defines the 'lower' border of the area.
See Also: XYStepAreaRenderer.setRangeBase(double) |
| initialise | | public XYItemRendererState initialise(Graphics2D g2, Rectangle2D dataArea, XYPlot plot, XYDataset data, PlotRenderingInfo info)(Code) | | Initialises the renderer. 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:
data - the data.
Parameters:
info - an optional info collection object to return data back to the caller. The number of passes required by the renderer. |
| restrictValueToDataArea | | protected static double restrictValueToDataArea(double value, XYPlot plot, Rectangle2D dataArea)(Code) | | 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 be
Parameters:
dataArea - the area within which the data is being drawn.
Parameters:
plot - the plot (can be used to obtain standard color information etc). double value inside the data area. |
| setPlotArea | | public void setPlotArea(boolean flag)(Code) | | Sets a flag that controls whether or not areas are drawn for each data
item.
Parameters:
flag - the flag.
See Also: XYStepAreaRenderer.getPlotArea() |
| setRangeBase | | public void setRangeBase(double val)(Code) | | Sets the value on the range axis which defines the default border of the
area. 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 borderof the area.
