title: Increasing scatter points marker size from a .fig file
body: <p>I have a figure file (scatter.fig) . This figure has many scatter points plotter using scatter(). Now i just have this fig file, I need to increase the marker size of all scatter points. Tried it manually but its very difficult. 
        Is there a way i can do something like 
          H=figurehandle()
          s= points(h)
          set(s,'markersize');</p>
  
  <p>I just could not figure out the exact commands.</p>
  
  <p>Thanks.</p>
