title: Plotting 3d position data over time
body: <p>I'm trying to plot the position of an object in 3D space (x, y and z co-ordinates) over time so that I can make predictions of the path the object might take.</p>
  
  <p>I'm attempting to do this in Matlab, but the question is more general than that. I'm finding it hard to visualise how this would work. I understand how one would plot x and y positions over time (and that would make a 3d graph), but how would I add a third dimension?</p>
  
  <p>I know about scatter3 in Matlab, but I need the motion to be a continuous line. Is this possible?</p>
  
  <p>Thanks!</p>
