/**
 * This is a helper method for creating charts and is split off as it does
 * only the chart creation and tweaking of a category chart. All of the
 * decisions for what columns are defined as what and how the data is stored
 * should be done in the method that calls this.
 * <p>//from w ww  .j  a  v a 2 s.  co m
 * Given a dataset and other chart properties this will create an
 * appropriate JFreeChart.
 * @param c 
 * 
 * @param dataset
 *            The data to create a chart from.
 * @param chartType
 *            The type of chart to create for the category dataset.
 * @param legendPosition
 *            The position where the legend should appear.
