Re: [Swarm-Support] Java Graphs

[durga bhavani]

Hello Marcus,

 

But when I change My progran this way it  is getting crashed and it's generating a log file. But I am unable to know why it is doing this.

Could you please take a look at this program at your convience and let me know where I am wrong.

 

 

Here are three Programs

1)Test.java

import swarm.Globals;
import swarm.defobj.Zone;
import swarm.gui.Graph;
import swarm.gui.GraphElement;
import swarm.gui.GraphImpl;
import swarm.simtoolsgui.GUISwarmImpl;
import swarm.objectbase.SwarmImpl;
import java.io.*;
import java.util.*;

public class Test extends SwarmImpl
{
public void Print1()
{
        String colors[]={"red","green","blue"};
        Graph graph1;
        try
        {
                System.out.println("Get the graph");
                TestObserver testObserver = new TestObserver(getZone());
                graph1 = testObserver.getgraph();
                testObserver.buildObjects();
                for (int i = 1; i < 8; i++) {
                System.out.println("Creating Graph Element");
                GraphElement ge = graph1.createElement ();
                ge.setLabel ("Time Step" + i);
                ge.setWidth (2);
                ge.setColor (colors[i % 3]);
                System.out.println(i);
                ge.addX$Y ((5 - i) ^ 2, 1 + i);
                ge.addX$Y (i + 9, 10 * Math.sin (Math.PI * i / 10));
                }
        }
        catch(Exception e)
        {
        System.out.println("Exception caught because of GroupObserver"+e);
        }
}
}

2) TestObserver.java

import swarm.Globals;
import swarm.simtoolsgui.GUISwarmImpl;
import swarm.defobj.Zone;
import swarm.gui.Graph;
import swarm.gui.GraphElement;
import swarm.gui.GraphImpl;
import swarm.Selector;

public class TestObserver extends GUISwarmImpl {
public Graph graph;
    TestObserver (Zone aZone) {
        super (aZone);
    }
public Graph getgraph(){
        return graph;
        }
    public Object buildObjects () {
        super.buildObjects ();
        String colors[] = { "red", "green", "blue" };
        graph = new GraphImpl (getZone ());
        graph.setWindowTitle ("A Graph");
        graph.pack ();
        return this;
        }
}

 

 

3)StartTest.java

 

import swarm.SwarmEnvironmentImpl;
import swarm.Globals;
import swarm.defobj.Zone;
import swarm.activity.ActionGroupImpl;
import swarm.activity.ActionGroup;
import swarm.activity.Activity;
import swarm.objectbase.SwarmImpl;
import swarm.objectbase.Swarm;
import swarm.Selector;
import java.util.LinkedList;
import java.util.List;

public class StartTest{
    public static void main (String args[]) {
        Globals.env.initSwarm ("Leader", "0.0", "address@hidden",args);
        TestObserver topLevelSwarm = new TestObserver(Globals.env.globalZone);
        Globals.env.setWindowGeometryRecordName(topLevelSwarm,"topLevelSwarm");
        System.out.println("Running Simulation");
        topLevelSwarm.buildObjects();
        topLevelSwarm.buildActions();
        topLevelSwarm.activateIn(null);
        Test test =  new Test();
        test.Print1();
        topLevelSwarm.go();
        System.out.println("Finished Main");
      //  topLevelSwarm.drop();

    }

}

 

Thanks a lot
