On your way in you may have missed that we have a policy on screen names here at JavaRanch. Basically, it must consist of a first name, a space, and a last name, and not be obviously fictitious. Since yours does not conform with it, please take a moment to change it, which you can do right here.
As to your question, describe in more detail what you're trying to do, and what the axes have to do with it. There are a number of things that would constitute "a zoom effect in an applet".
