Parameters:
dataArea - the area within which the plot is being drawn.
Parameters:
info - collects info about the drawing.

| initialise | | public XYItemRendererState initialise(Graphics2D g2, Rectangle2D dataArea, XYPlot plot, XYDataset dataset, PlotRenderingInfo info)(Code) | | Initialises the renderer then returns the number of 'passes' through the
data that the renderer will require (usually just one). 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:
dataset - the data.
Parameters:
info - an optional info collection object to return data back to the caller. The number of passes the renderer requires. |

to close and sends a
RendererChangeEvent to all registered
listeners.
Parameters:
paint - The paint (null permitted). |
| setUseOutlinePaint | | public void setUseOutlinePaint(boolean use)(Code) | | Sets the flag that controls whether or not the renderer's outline
paint is used to draw the candlestick outline, and sends a
RendererChangeEvent to all registered listeners.
Parameters:
use - the new flag value.
since:
1.0.5
