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);
