[Plplot-general] (no subject)

[<so...@sy...>]

Hi Arjen,

I am trying to open up more than one plot. It looks like octave binding does allows this but I have not been able to do it so far. 

I am using one thread per plot. Is there any example or sample explaining how to launch multiple plots?

I tried the following test program. 

/*
 * Created on Nov 5, 2004
 *
 */
package plplot.examples;

import plplot.core.PLStream;

/**
 * @author Ali
 *
 */
public class Test extends Thread {

 static {
  System.load("c:\\jmatlab\\jmatlab\\jplplot.dll");
 }
 
 public void run() {
  PLStream pls = new PLStream();
  pls.sdev("win3");
  pls.init();
  double[] x = new double[] {1.0, 2.0, 3.0};
  double[] y = new double[] {1.0, 2.0, 3.0};
  pls.col0(1);
        pls.env(0.0, 10.0, 0.0, 10.0, 0, 1);
        pls.col0(2);
  pls.poin(x, y, 0);
  pls.flush();
  pls.end1();
 }
 
 public static void main(String[] args) {
  Test t = new Test();
  t.start();
  t = new Test();
  t.start();
 }
}


In run mode only one one shows up and when I close the window I get following error message. 

*** PLPLOT ERROR ***

plcol0: Please call plinit first, aborting operation

*** PLPLOT ERROR ***

plenv: Please call plinit first, aborting operation

*** PLPLOT ERROR ***

*** PLPLOT ERROR ***

plstyl: Please call plinit first, aborting operation

*** PLPLOT ERROR ***

plpat: Please call plinit first, aborting operation

In the debug mode, it shows both plots and one closing them I get following errors

An unexpected exception has been detected in native code outside the VM.
