the class JFreeChartInfo method drawTitle.

/**
 * Draws a title.  The title should be drawn at the top, bottom, left or

 * @param t  the title (<code>null</code> not permitted).
 * @param g2  the graphics device (<code>null</code> not permitted).
 * @param area  the chart area, excluding any existing titles
 *              (<code>null</code> not permitted).
 * @param entities  a flag that controls whether or not an entity
 *                  collection is returned for the title.
 *
 * @return An entity collection for the title (possibly <code>null</code>).
