Dear All,

I have a figure containing several linked objects (a plot3 surface, a plot3 set of 3D points, and a set of associated text labels), the latter two plotted in a for loop as they are linked. Here is the relevant code:

    ...
    h1=plot(surface...);
    for j = 1:length(points)
    h2=plot3(points(j,1),points(j,2),points(j,3),...,'MarkerSize',x);   
    hold on
    h3=text(points(j,1),points(j,2),points(j,3),...,num2str(Text(j)));
    set(h3,'FontSize',y,...);
    ...

I want to normalize x and y to figure axes (say ax) sizes (1) and dynamically adapt them to ax size changes (2). I was suggested to use ResizeFcn, but I got stuck. Here are my trials for (1):

    ...
    ax=gca;
    curunits = get(ax, 'Units');
    set(ax, 'Units', 'Points');
    % pos_ax=get(ax,'Position'); 
    set(ax, 'Units', curunits);
    relativesize = 0.05;    
    set(h2,'MarkerSize', pos_ax(3)*relativesize);
    set(h3,'FontSize', pos_ax(3)*relativesize);
    ...
