How to add jfreechart to jPanel?
Hello everyone,
The question is, how to add graph generated by JFreeChart to a jPanel?
I have a Graph class, that generates graph:
Code:
package epidemics;
import java.io.File;
import java.io.IOException;
import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartUtilities;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.data.xy.XYSeries;
import org.jfree.data.xy.XYSeriesCollection;
public class Graph {
public Graph(Data data) {
//XYSeries series1 = new XYSeries("Healthy People");
//XYSeries series2 = new XYSeries("Sick People");
//XYSeries series3 = new XYSeries("Recovered People");
//System.out.println(data.getDuration());
for (int i = 0; i < data.getD(); i++) {
//System.out.println(data.getHppl(i) + " " + data.getSppl(i) + " " + data.getMonth(i));
series1.add((i), data.getS(i));
series2.add((i), data.getI(i));
series3.add((i), data.getR(i));
}
dataset.addSeries(series1);
dataset.addSeries(series2);
dataset.addSeries(series3);
//JFreeChart chart = ChartFactory.createXYLineChart ("Graph", "time", "individuals", dataset, PlotOrientation.VERTICAL, true, true, false);
chart = ChartFactory.createXYLineChart ("Graph", "time", "individuals", dataset, PlotOrientation.VERTICAL, true, true, false);
try {
ChartUtilities.saveChartAsJPEG(new File("d:\\graph.jpg"), chart, 500, 300);
}
catch (IOException e) {
System.err.println("Problem occurred creating chard.");
}
}
public JFreeChart drawChart() {
return chart;
}
private XYSeries series1 = new XYSeries("Healthy People");
private XYSeries series2 = new XYSeries("Sick People");
private XYSeries series3 = new XYSeries("Recovered People");
private XYSeriesCollection dataset = new XYSeriesCollection();
JFreeChart chart;
}
When I create an object of Graph, it creates a picture in a file. I want to add this graph to a jPanel, not save it as a picture.
I tried to do it, but it does not seem to work:
Code:
Graph graph = new Graph(data);
JFreeChart chart;
chart = graph.drawChart();
ChartPanel chartPanel = new ChartPanel(chart);
jPanel1.add(chartPanel);
Could someone please advise me how to solve this problem?
Thanks in advance!
