the class DeviationRenderer method drawItem.

/**
 * Draws the visual representation of a single data item.

 * @param g2  the graphics device.
 * @param state  the renderer state.
 * @param dataArea  the area within which the data is being drawn.
 * @param info  collects information about the drawing.
 * @param plot  the plot (can be used to obtain standard color
 *              information etc).
 * @param domainAxis  the domain axis.
 * @param rangeAxis  the range axis.
 * @param dataset  the dataset.
 * @param series  the series index (zero-based).
 * @param item  the item index (zero-based).
 * @param crosshairState  crosshair information for the plot
 *                        (<code>null</code> permitted).
 * @param pass  the pass index.
