JFreeChart With Threads

[yprabathme]

I have tried to assign the JFree chart meters with Threads. But not get the value. Pls help me. This is the code I have written.


import javax.swing.JFrame;
//Meters Class

class MyshowMeters extends Thread {

int xpos = 100;
int ypos = 50;
float meterval1;
float meterval2;
float meterval3;

public void getArray(float f1,float f2,float f3){
meterval1 = f1;
meterval2 = f2;
meterval3 = f3;
}

public void run() {
Meters meter1 = new Meters("Meter 1");
meter1.pack();
meter1.setLocation(xpos, ypos);
meter1.setAlwaysOnTop(true);
meter1.setVisible(true);

Meters meter2 = new Meters("Meter 2");
meter2.pack();
meter2.setLocation(xpos, ypos + 320);
meter2.setAlwaysOnTop(true);
meter2.setVisible(true);

Meters meter3 = new Meters("Meter 3");
meter3.pack();
meter3.setLocation(xpos + 320, ypos );
meter3.setAlwaysOnTop(true);
meter3.setVisible(true);

while (true){
meter1.setdataset(meterval1);
meter2.setdataset(meterval2);
meter3.setdataset(meterval3);

//meterval1,2,3 values are not assign from the getArray method

}
}
}

//here, I wants to pass the getArray values to run() but it not happen..

Since you're calling Swing code, you should not do this on a background thread, but rather on the EDT or event dispatch thread. The Sun Swing tutorials can tell you more about this. I have a feeling though that this is not the cause of your current problems though, but rather the while(true) is likely squashing your Swing thread. Please read this:
