Dynamically plot graphs to axes component

Is it possible to dynamically add a number of "axes components" onto a GUIDE fig. I want to display a graph of data for each file in a directory. But this number can vary. Sometimes 2, sometimes 6. Thanks

Just use the subplot function
To remove all the subplots from your GUI do this:
delete(findall(gcf,'type','axes'))

Is there a fixed total size in which all the plots are to go? If so then subplot() . Or is the figure to grow to fit the plots? If so, what if you run out of screen? Is a new figure to be created for each plot? Or do you want to use fixed size per plot but have the area scrollable to see the other plots?

Yes there is, the size of my form I use in GUIDE. Yes a fixed size per plot with screen scrolling is desirable.

You can use the axes command. You'll probably want to set the 'Position' property, and store the handle to the axes in the handles structure.
handles.axes1 = axes('Position', [x1 y1 w1 h1]);
handles.axes2 = axes('Position', [x2 y2 w2 h2]);
...
When you need to remove an axes from the GUI, you should pass the axes handle to the delete function:
delete(handles.axes1);

how can I have handles.axesi where i is a variable? This depends on the number of file sin the directory which can change.

You could also store all the axes handles together in a cell array as one field in the handles structure:
handles.axes{1} = axes( ... );
handles.axes{2} = axes( ... );
