Hi

I have 35 lakes location(x and y) and the size of lakes(in km) on my third column. How I can plot the lakes with corresponding size? I am supposed to get 35 different size of circles;smaller, bigger and very big circles.

Thanks a lot!

在 MATLAB Online 中打开

    for idx=1:length(lake)
      px = lake(idx,1)-lake(idx,3);
      py = lake(idx,2)-lake(idx,3);
      d = lake(idx,3)*2;
      h = rectangle('Position',[px py d d],'Curvature',[1,1]);
      daspect([1,1,1])
      hold on
    end
