What error or action occurs when you do exactly what you just said?

Two things, because my second coffee hasn't kicked in yet. 1. Use a descriptive subject line (not "Urgent") and/or tag the message with keywords. 2. This is not - by any possible stretch of the imagination - urgent.

Since this sounds like you're working with a GUI you've been given, I would contact the author of that GUI and ask them for clarification and/or to include more information about what specifically you need to do in the message box. > what is the condition to check whether the axes box is empty or not... There is no such condition (short of doing some serious image processing, and even that wouldn't always work.) You could check if the axes has no children, but what if an object on another axes overlaps that axes? What if that overlapping object is the same color as the axes it's overlapping -- does that count as an empty "axes box" or not? And I agree with Mark's first comment -- you should definitely use a more specific subject line than "Urgent". Make your post stand out by giving it a clear, yet descriptive subject -- something like "How can I determine if my axes box is empty?" would probably draw more attention from people interested in helping with graphics questions. -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ
