title: matlab animate 2 3d plots in same figure, have hold on one and not the other
body: <p>For my current project in matlab i am modeling the spread of an infection across the globe. the main method i am using for letting the infection jump is pre-set airport locations.  I also  show when the infection spreads from airport to airport by connecting them with animated lines.  The main map is a 3d surf graph set to default 2D view and the lines are graphed using plot3, which is also in the 2D view. </p>
  
  <p>I have everything working except for one problem.  I need to animate both 3D graphs at the same time in the same figure but I need to let hold not be on for the animation of the map while allowing hold to be on for the animation of the lines connecting airports so that all of the paths will still be shown.</p>
  
  <p>Any ideas on how to do this?</p>
