[EDIT: 20110512 17:01 EDT - reformat - WDR]

Dear fellow MATLAB Users,

I have created a dynamic plotting system, and would like for the resulting plots to build upon one another. My current code places each plot on a predetermined grid space without affecting each other. Here is the code associated with my issue:

______________________

z=zeros(1,3);
xD=[10;30;35];
yD=[10;30;35];
for i=1:3
[x,y] = meshgrid(-10:0.2:50);
z=42 - 4.2*sqrt((x-xD(i)).^2+(y-yD(i)).^2);
z(z<0) = 0;
surf(x,y,z,'linestyle','none');
drawnow;
pause(1);
hold on
end

______________________

I would greatly appreciate any help that could be given to help remedy my issue!

Thanks,

~ Chris

This is an example of where the plots add on top of each other:

xD = 100*randn(1,1000);
yD = 100*randn(1,1000);
[x,y] = meshgrid(-10:0.2:50);
z_sum = 0*x;
h = surf(x,y,z_sum,'linestyle','none');
for i=1:numel(xD);
      z=42 - 4.2*sqrt((x-xD(i)).^2+(y-yD(i)).^2);
      z(z<0) = 0;
      z_sum = z_sum + z;
      set(h,'zdata',z_sum);
      drawnow;
end
