Multiple surface plots on a single figure

I am trying to make several figures with multiple surface plots on each. Not using subplot or anything, just a bunch of different-colored shells overlapping each other on one figure. What I've been trying to work with is:

for c = 1:figum
  figure(c)
  resolution = 50;
  theta = linspace(1.7, 2.6, res);
  phi = linspace(-.1, 0.8, res);
  [theta, phi] = meshgrid(theta, phi);
  hold on

    for c = 1:10
      %Calculate r values based on model parameters
      [x, y, z] = sph2cart(theta, phi, r);
      surf(x,y,z,(ones(size(x))*c))
    end

    hold off
    legend('1','2','3','4','5','6','7','8','9','10')
  end

But all I'm getting from this is Figure 1 with the tenth surface for the last figure, and then blank figure windows for the higher numbered figures in the loop. Any ideas why it seems to be skipping my hold on commands AND my new figure commands and just overwriting everything on the first figure?

Thanks in advance!

Perhaps you want figure(c) instead of figure(fignum), since fignum is a constant?

I also recommend you read my remarks in http://www.mathworks.com/matlabcentral/answers/22208-show-figure

Using the constant was an accidental side effect of my condensing two function's worth of material into a quick form to post on here. The real code is advancing in the loop properly.

I tried doing what you suggested, so what I basically do is

for c = 1:fignum

f = figure();

ax = axes('Parent',f);

plotsurface(ax)

end

Where plotsurface then uses

hold on

for c = 1:10

surf(ax, x, y, z, (ones(size(x))*c)

end

hold off

But I'm still getting the same issue, several blank figures and Figure 1 having the shape number 10 in it with nothing else, even though the legend indicates there should be all 10 shapes.
