Dear Li An,
I assume you're using the Java collections LinkedList rather than the
Swarm one. In this case the following example code should help you. What you
do is simply create a graph object and tell it to plot the results of
calling the size() method on your LinkedList. If you prefer to use the Swarm
LinkedList replace size() with getCount(). Don't forget to schedule the
step() method on the graph regularly.
The main thing to remember is you can use an EZGraph to create a sequence
from pretty much any object using pretty much any method.
James
LinkedList list = new LinkedList();
EZGraphImpl graph = new EZGraphImpl(getZone(), "List size", "Time", "Size",
listSizeGraph");
graph.createSequence$withFeedFrom$andSelector("list size", list, new
Selector(list.getClass(), "size", false));

Subject: Re: [Swarm-Support] EZGraph
Sounds good. Does EZgraph have a method to graph what I get using
getSizeOfList (y-axis) over time (x-axis)?
