Re: Display problem

[Paul E. Johnson]

I have an example that does this. In 

In the middle of buildObjects, I have this:

  stabilityGraph = [EZGraph createBegin: [self getZone]];
  SET_WINDOW_GEOMETRY_RECORD_NAME (stabilityGraph);
  [stabilityGraph setTitle: "Membership"];
  [stabilityGraph setAxisLabelsX: "time" Y: "Total Membership"];
  stabilityGraph = [stabilityGraph createEnd];




-createMembershipSequence: (id) aRecruiter
{
  id sequence;
  char sequenceName[10];
  sprintf(sequenceName,"Org. %d",[aRecruiter getGrpNumber]);
  sequence= [stabilityGraph createSequence: sequenceName
                            withFeedFrom: aRecruiter
                            andSelector: M(getMembershipLevel)];
  return sequence;
}

-dropMembershipSequence: (id) aRecruiter
{
  [stabilityGraph dropSequence:  aRecruiter];
  return self;
}


In ModelSwarm.m, when agents are created, the method doing the creating
tells the observer to create a sequence and return a pointer to it, that
way when they die they can tell the graph to remove that sequence. When
they are created, that method in modelswarm does this:

   [recruiter setMembershipSequence:
               [observerSwarm createMembershipSequence: recruiter]];

When they die, they do this:
   [observerSwarm dropMembershipSequence: [agent
getMembershipSequence]];



And within the Agent, all they need is set and get methods for the
sequence, as in:>
-setMembershipSequence: (id) aSeq
{
  memSequence=aSeq ;
  return self;
}

-getMembershipSequence
{
  return memSequence;
}


This design is required because agents are killed and born.
