As far as I can see, this example works as expected in my linux. Maybe 
this is a local problem. I see squares and not circles.

I can reproduce this. Point dimensions are proportional to the window 
size, but this is not bad.

This is not the answer to your question, but another way to get a 
similar plot:

xy:[[10,.6], [20,.9], [30,1.1], [40,1.3], [50,1.4]]$

load(draw)$

draw2d(
  yrange = [0,1.6],
  color = blue,
  key  = "theory",
  explicit(2*%pi*sqrt(l/980),l,0,50),

  color = red,
  key   = "experiment",
  point_type = filled_square,
  point_size = 3,
  points(xy)  )$


hth.
