How do I plot a temporary variable in a parfor loop?

Hi,
I'm trying to make a surf plot with a parfor loop:
figure();
hold on
view(3)
[x,y,z]=sphere;
h=waitbar(0,'Please wait, generating figure');
for i=1:N
for r=linspace(.1,15,40) % sphere radius
clr=colormap(jet(N_unique));
h=surf(XFoci(i) + r*x,YFoci(i) + r*y,ZFoci(i) + r*z,'facecolor',clr(ic(i),:),'edgecolor','none');
alpha(h,(1./(r+1)));
end % for r=linspace(.1,10,40) % sphere radius
end % for i=1:N
Other than the fact that I have to change r to be integer numbers (no problems), I'm not sure how to parallelize the surf ploting using parfor.
Thanks, Guy

Unfortunately, parallel pool workers are separate MATLAB processes, and they cannot access the same figure handles that your desktop MATLAB client creates. Workers can create graphics, but each worker does so independently, so you cannot have multiple workers collaborate on a figure. After a worker has produced graphical output, the next step is to use print to output it to a file - workers cannot display graphics on-screen.

Thanks Edric, but I am interested in printing 1 figure which is the output of all workers. I did however created a cell array of spheres in parallel, and then plot the cell array with surf not in parallel.
