MATLAB GUI loading unwanted data

I created a GUI using GUIDE, and at some point I must've saved settings or something. The GUI has a plot window that should be blank when the GUI loads, but it has data in it on load. However, when I check in the Properties, there's no UserData. This isn't the only element to reset to some unknown state, elements that shouldn't be populated are when first loaded. It seems like some sort of settings are being loaded on initialization, but I can't find where. Can anybody help with this?

An axes will have properties that you can pre-set in GUIDE, but it will have no data unless you put it in. In your openingFcn, you must be assigning something to the GUI, perhaps after you call a load(), or maybe you just hard coded something in. Step though the function one line at a time until you find the statement that does it. http://blogs.mathworks.com/videos/2012/07/03/debugging-in-matlab/

Huh? You don't load a .fig file as you would a .mat file. A mat file is a binary file (propeitary format) with a bunch of variables in it. A .fig file is a file created by GUIDE that tells MATLAB how to build a GUI. You shouldn't load a .fig file as a .mat file. Why don't you attach your m-file, fig-file, and any mat or data files using the paperclip icon so people can try them?

I used hgload and hgsave, is that not what they are used for? Either way, I got it fixed, thanks for the help.
