Displaying graphics from non-GUI swarm?

[Jae Chan Oh]

Hi,
I would like to display a transient data in a histogram.
This means the data that are only available within ModelSwarm and disappears 
for each step of ModelSwarm. It is for specifically, the data, say some gene 
value, in reaperQueue for dying people.

Now, I have tried to send the ptr of reaperQueue to ObserverSwarm (a GUI swarm)
but when ObserverSwarm' action are activated the reaperQueue is empty. 
Therefore,
I get an empty histogram for each step.

Then I tried to schedule actions to display for this particular histogram 
as part of ModelSwarm actions not as part of ObserverSwarm, but no luck either.

Now I am trying to create/declare all about this histogram display within
ModelSwarm. However, I can't declare "EZBin * reaperQHistogram" within 
ModelSwarm since ModelSwarm is not a GUI swarm.

Any suggestions?

Thank you,

-Jae
