JFreeChart在制作折线图

JFreeChart在制作折线图的时候可以使用两种不同的方式

 

package Line;

import java.awt.Color;
import java.awt.Font;
import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartFrame;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.StandardChartTheme;
import org.jfree.chart.plot.CategoryPlot;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.data.category.CategoryDataset;
import org.jfree.data.category.DefaultCategoryDataset;

public class Line {
  public static void main(String[] args) {
    StandardChartTheme mChartTheme = new StandardChartTheme("CN");
    mChartTheme.setLargeFont(new Font("黑体", Font.BOLD, 20));
    mChartTheme.setExtraLargeFont(new Font("宋体", Font.PLAIN, 15));
    mChartTheme.setRegularFont(new Font("宋体", Font.PLAIN, 15));
    ChartFactory.setChartTheme(mChartTheme);		
    CategoryDataset mDataset = GetDataset();
    JFreeChart mChart = ChartFactory.createLineChart(
        "折线图",//图名字
        "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;
  }


}


第二种方式：

 

package Line;

import java.awt.Font;

import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartFrame;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.StandardChartTheme;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.data.xy.XYSeries;
import org.jfree.data.xy.XYSeriesCollection;

public class XYLine {
  public static void main(String[] args) {
    StandardChartTheme mChartTheme = new StandardChartTheme("CN");
    mChartTheme.setLargeFont(new Font("黑体", Font.BOLD, 20));
    mChartTheme.setExtraLargeFont(new Font("宋体", Font.PLAIN, 15));
    mChartTheme.setRegularFont(new Font("宋体", Font.PLAIN, 15));
    ChartFactory.setChartTheme(mChartTheme);		
    XYSeriesCollection mCollection = GetCollection();
    JFreeChart mChart = ChartFactory.createXYLineChart(
        "折线图",
        "X",
        "Y",				
        mCollection,
        PlotOrientation.VERTICAL,
        true, 
        true, 
        false);
    ChartFrame mChartFrame = new ChartFrame("折线图", mChart);
    mChartFrame.pack();
    mChartFrame.setVisible(true);

  }	
  public static XYSeriesCollection GetCollection()
  {
    XYSeriesCollection mCollection = new XYSeriesCollection();
    XYSeries mSeriesFirst = new XYSeries("First");
    mSeriesFirst.add(1.0D, 1.0D);
      mSeriesFirst.add(2D, 4D);
      mSeriesFirst.add(3D, 3D);
      mSeriesFirst.add(4D, 5D);
      mSeriesFirst.add(5D, 5D);
      mSeriesFirst.add(6D, 7D);
      mSeriesFirst.add(7D, 7D);
      mSeriesFirst.add(8D, 8D);
      XYSeries mSeriesSecond = new XYSeries("Second");
      mSeriesSecond.add(1.0D, 5D);
      mSeriesSecond.add(2D, 7D);
      mSeriesSecond.add(3D, 6D);
      mSeriesSecond.add(4D, 8D);
      mSeriesSecond.add(5D, 4D);
      mSeriesSecond.add(6D, 4D);
      mSeriesSecond.add(7D, 2D);
      mSeriesSecond.add(8D, 1.0D);
    mCollection.addSeries(mSeriesFirst);
    mCollection.addSeries(mSeriesSecond);
    return mCollection;
  }

}

 平面折线图效果

 

 

3D折线图效果:

 

 

设置线条、数据点颜色和显示属性

CategoryPlot mPlot = (CategoryPlot)mChart.getPlot();
mPlot.setBackgroundPaint(Color.WHITE);// 设置绘图区背景色
mPlot.setRangeGridlinePaint(Color.BLUE);//背景底部横虚线
mPlot.setOutlinePaint(Color.RED);//边界线
mPlot.setDomainGridlinePaint(Color.BLUE); // 设置垂直方向背景线颜色
mPlot.setDomainGridlinesVisible(true); // 设置是否显示垂直方向背景线,默认值为false

LineAndShapeRenderer lasp = (LineAndShapeRenderer) mPlot.getRenderer();// 获取显示线条的对象
lasp.setBaseShapesVisible(true);// 设置拐点是否可见/是否显示拐点
lasp.setDrawOutlines(true);// 设置拐点不同用不同的形状
lasp.setUseFillPaint(true);// 设置线条是否被显示填充颜色
lasp.setBaseFillPaint(Color.BLACK);//// 设置拐点颜色
//lasp.setSeriesPaint(series, paint);
