import org.jfree.chart.renderer.category.LineAndShapeRenderer; //導入方法依賴的package包/類
/**
 * Creates a line chart with default settings.  The chart object returned
 * by this method uses a {@link CategoryPlot} instance as the plot, with a
 * {@link CategoryAxis} for the domain axis, a {@link NumberAxis} as the
 * range axis, and a {@link LineAndShapeRenderer} as the renderer.
 *
 * @param title  the chart title ({@code null} permitted).
 * @param categoryAxisLabel  the label for the category axis
 *                           ({@code null} permitted).
 * @param valueAxisLabel  the label for the value axis ({@code null}
 *                        permitted).
 * @param dataset  the dataset for the chart ({@code null} permitted).
 * @param orientation  the chart orientation (horizontal or vertical)
 *                     ({@code null} not permitted).
 * @param legend  a flag specifying whether or not a legend is required.
 * @param tooltips  configure chart to generate tool tips?
 * @param urls  configure chart to generate URLs?
 *
 * @return A line chart.
