MATLAB: Can figure numbers be re-assigned

figure

Is it possible to re-assign a figure number , for example if I have a Figure 55 open, can I make it Figure 2 as long as I don't already have a Figure 2 open? If so how do I do this?

I have a routine that generates 60+ figures, and I delete all but 3 interesting ones. I would like to make them Figures 1,2,3 because I need to re-run the routine and generate another set of figures, and I'd like the first set to appear together in the figure order (it makes them easier to keep track of).

To get a list of all the existing figures:

 get(0,'Children');

If figure two does not exist and you want to copy figure(55):

 figure(2)
 copyobj(allchild(55),2);

Get rid of figure(55):

 clf(55);

And to answer your question directly. I believe once a figure number is set, you have to live with it. But there are workarounds, such as the one above.

When you do allchild(figList(iOld)), you are copying everything. That includes the uicontrols and menu. That is the source of the error. If you only want to copy the graphics objects, you could do as follows (will copy only the 'axes' objects):

for ii = 1:10
    plot(rand(10,1));
end
% Get a list of all existing figures
figList = sort(get(0,'Children'));
for iOld = 1:length(figList)
    figOld = figList(iOld); % This is a figure to replace
        % Used later to make sure size of figure is correct
        posOld = get(figOld, 'pos'); 
        figNew = figure; % Make new figure
        % Used later to make figure appear at  
        % default horizontal position on screen
        posNew = get(figNew, 'pos'); 
        % Copy over lines (but not formatting)
        %Copy only the axes %This is the new bit
        kids = allchild(figList(iOld));
        type = get(kids,'Type');
        idx = strcmp(type,'axes');       
        copyobj(kids(idx),figNew); 
        % Reproduce figure name and size however don't move it horizontally
        set(figNew, 'Name', get(figOld, 'Name'), ...
            'pos', [posNew(1:2) posOld(3:4)]);
        % Get rid of old figure
        close(figList(iOld));
    end
