What is "the gui variable"? Do you mean the handles struct? Then:
handles.yourData = [];
guidata(hObject, handles);
Or
handles = rmfield(handles, 'yourData');
guidata(hObject, handles);
Or perhaps some persistent variables?
For a more precise answer, explain, how you store the variables.

hello @Jan
I have a little problem. I was able to code a "Next button" using app designer that have as aim to draw lines. I had the data coming from excel. I am able to draw each line by clicking on the next button. The only problem is that the previous data/line is not deleted. So instead of having one line, i will have 2 or more depending on how many times i click on the next button.
any function hat could be helpful?
