title: Changing scaling of MATLAB Figure
body: <p>I have a figure that displays 20,000 points on the x-axis. So it
  labels the x-axis from 0 ... 20,000. However, now I would like to scale 
  it from 0 to 50. But when I try to do this in the plot window it just
  shows me the first 50 points, instead of changing the scale. Is there
  any straightforward way to do that in MATLAB?</p>
