                "年份",//横坐标
                "数量",//纵坐标
                mDataset,//数据集
                PlotOrientation.VERTICAL,
                true, // 显示图例
                true, // 采用标准生成器
                false);// 是否生成超链接

        CategoryPlot mPlot = (CategoryPlot)mChart.getPlot();
        mPlot.setBackgroundPaint(Color.LIGHT_GRAY);
        mPlot.setRangeGridlinePaint(Color.BLUE);//背景底部横虚线
        mPlot.setOutlinePaint(Color.RED);//边界线

        ChartFrame mChartFrame = new ChartFrame("折线图", mChart);
        mChartFrame.pack();
        mChartFrame.setVisible(true);

    }
    public static CategoryDataset GetDataset()
    {
        DefaultCategoryDataset mDataset = new DefaultCategoryDataset();
        mDataset.addValue(1, "First", "2013");
        mDataset.addValue(3, "First", "2014");
        mDataset.addValue(2, "First", "2015");
        mDataset.addValue(6, "First", "2016");
        mDataset.addValue(5, "First", "2017");
        mDataset.addValue(12, "First", "2018");
        mDataset.addValue(14, "Second", "2013");
        mDataset.addValue(13, "Second", "2014");
        mDataset.addValue(12, "Second", "2015");
        mDataset.addValue(9, "Second", "2016");
        mDataset.addValue(5, "Second", "2017");
        mDataset.addValue(7, "Second", "2018");
        return mDataset;
    }
}

效果图如下：
