I have a problem using JFreeChart with JavaFX. I wrote a small program here to help explain.
At first the graph likes this:
I use fullScreen function to display the JFreeChart Line Chart Demo 2. Here I use SwingNode, ChartPanel to embedded JFreeChart into JavaFX Panel.(Detail part will be included in code later)
Then I press ESC to exit fullScreen. Then it looks like this:
So far, it's as expected. Then I use mouse drag to enlarge the window. Here comes the problem, as the following picture.
Can you see that, seems like appear another graph. And I must click on the window, then everything will become good.So my question is: anyone knows why? I wish the graph shows well even when I drag the window to enlarge, is there something I missed?
And here is my code:
package testxychart;
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

/** * * @author Administrator */
public class TestXYChart extends Application {
NumberAxis xAxis = new NumberAxis();
NumberAxis yAxis = new NumberAxis();
XYChart.Series series1 = new XYChart.Series();
@Override public void start(Stage primaryStage) {
SplitPane vSplitPane = new SplitPane();
vSplitPane.getItems().add(this.creatChart1());
primaryStage.setScene(new Scene(vSplitPane));
primaryStage.setFullScreen(true);
primaryStage.show();
}
private SwingNode creatChart1(){
XYSeries series1 = new XYSeries("First");
series1.add(1.0, 1.0);
series1.add(2.0, 4.0);
series1.add(3.0, 3.0);
series1.add(4.0, 5.0);
series1.add(5.0, 5.0);
series1.add(6.0, 7.0);
series1.add(7.0, 7.0);
series1.add(8.0, 8.0);
XYSeries series2 = new XYSeries("Second");
series2.add(1.0, 5.0);
series2.add(2.0, 7.0);
series2.add(3.0, 6.0);
series2.add(4.0, 8.0);
series2.add(5.0, 4.0);
series2.add(6.0, 4.0);
series2.add(7.0, 2.0);
series2.add(8.0, 1.0);
XYSeries series3 = new XYSeries("Third");
series3.add(3.0, 4.0);
series3.add(4.0, 3.0);
series3.add(5.0, 2.0);
series3.add(6.0, 3.0);
series3.add(7.0, 6.0);
series3.add(8.0, 3.0);
series3.add(9.0, 4.0);
series3.add(10.0, 3.0);
XYSeriesCollection dataset = new XYSeriesCollection();
dataset.addSeries(series1);
dataset.addSeries(series2);
dataset.addSeries(series3);
JFreeChart chart = ChartFactory.createXYLineChart( "Line Chart Demo 2", // chart title
"X", // x axis label
"Y", // y axis label
dataset, // data
PlotOrientation.VERTICAL, true, // include legend
true, // tooltips
false // urls
);
ChartPanel chartPane = new ChartPanel(chart);
SwingNode sNode = new SwingNode();
sNode.setContent(chartPane);
return sNode;
}
/** * @param args the command line arguments */
public static void main(String[] args) {
launch(args);
}
}
Thank you so much for any advice. I think, when I use several graphs in one JavaFX Panel, this will becomes a big problem.
