/**    
 * Draws the item (first pass). This method draws the lines    
 * connecting the items. Instead of drawing separate lines,    
 * a GeneralPath is constructed and drawn at the end of    
 * the series painting.    /*from   w  w w.j a v a 2  s .c o m*/
 *    
 * @param g2  the graphics device.    
 * @param state  the renderer state.    
 * @param plot  the plot (can be used to obtain standard color information    
 *              etc).    
 * @param dataset  the dataset.    
 * @param pass  the pass.    
 * @param series  the series index (zero-based).    
 * @param item  the item index (zero-based).    
 * @param domainAxis  the domain axis.    
 * @param rangeAxis  the range axis.    
 * @param dataArea  the area within which the data is being drawn.
