If you have, say, 10 items in a list and you want them to append 10
points to the *same* line, the existing EZGraph API isn't going
to do it. You'd need to subclass EZGraph and add a new
createGraphSequence:forSequence:withFeedFrom:andSelector: method that
created a subclass of ActiveGraph which had a -step method which would
handle lists. Actually, you could probably do it without a EZGraph subclass
if you did a +poseAs: for the modified ActiveGraph class.
However, if you are happy to plot 10 different lines, then see Paul's message.
