I have a project that uses JFreeChart.
The chart that I am using is displaying correctly and works fine with the current code.
My problem is that I can only position the graph to the east, south, west, center or north of my JPanel.
My desire is to move this chart to any position inside my JPanel.
This is the short code snippet where I add my graph to the panSimulator JPanel. The problematic code is at the bottom of the ConfigurationFrame class:
public class ConfigurationFrame extends JFrame {
private KettlerBikeConnector bike1 = null;

private Timer timerBike;
private TimerListener listener;
private final int UPDATE_MS = 1000; // updates every second
private JTabbedPane tabPane;
private JPanel panConfiguration;
private JPanel panGame;

And this class belongs to my chart that I want to move to any location in my JPanel.
public class CrosshairDemo extends JFrame {

public void setPower(double power) {
POWER = power;
}
public CrosshairDemo() {
super();
this.setContentPane(new CrosshairDemo.MyDemoPanel());
}
public static class MyDemoPanel extends JPanel implements Runnable {
/**

private static final long serialVersionUID = 1L;
Thread t = new Thread((Runnable) this);
private TimeSeries series;
private final ChartPanel chartPanel;
private final JFreeChart chart = this.createChart();
public MyDemoPanel() {
super(new BorderLayout());
this.chartPanel = new ChartPanel(this.chart);
this.chartPanel.setPreferredSize(new Dimension(200, 550));
this.chartPanel.setLocation(getWidth() + 50, getHeight() + 30);
this.chartPanel.setDomainZoomable(true);
this.chartPanel.setRangeZoomable(true);
this.add(this.chartPanel);
t.start();
}
private JFreeChart createChart() {
XYDataset dataset1 = this.createDataset("Random 1", 100.0D, new Minute(), 200);
JFreeChart chart1 = ChartFactory.createTimeSeriesChart("Crosshair Demo 1", "Time of Day", "Value", dataset1);
XYPlot plot = (XYPlot)chart1.getPlot();
plot.setOrientation(PlotOrientation.VERTICAL);
plot.setDomainCrosshairVisible(true);
plot.setDomainCrosshairLockedOnData(false);
plot.setRangeCrosshairVisible(false);
return chart1;
}
private XYDataset createDataset(String name, double base, RegularTimePeriod start, int count) {
this.series = new TimeSeries(name);
RegularTimePeriod period = start;
double value = base;
for(int i = 0; i < count; ++i) {
this.series.add(period, value);
period = period.next();
value *= 1.0D + (Math.random() - 0.495D) / 10.0D;
}
TimeSeriesCollection dataset = new TimeSeriesCollection();
dataset.addSeries(this.series);
return dataset;
}
@Override
public void run() {
// TODO Auto-generated method stub
while(true) {
int value = (int) POWER; //this.slider.getValue();
XYPlot plot = (XYPlot)this.chart.getPlot();
ValueAxis domainAxis = plot.getDomainAxis();
Range range = domainAxis.getRange();
double c = domainAxis.getLowerBound() + (double)value / 100.0D * range.getLength();
plot.setDomainCrosshairValue(c);
}
}
}
Right now it's "attached" to the top (NORTH) of my JPanel:
Current chart position:
I would appreciate any help, because I have no more idea how to position this chart freely, therefore, I need your help guys.
