title: Plotting specific range of values within an array Pyplot
body: <p>I want to plot a certain range of values within 2 arrays using matplotlib, </p>
  
  <pre><code>seconds = 200
  dt = .001
  x = array of values
  time = arange(0, seconds, dt)
  </code></pre>
  
  <p>Goal is to plot everything after the first 25 seconds. I Know I could create 2 new arrays using a for loop, but I'm certain there's some simple built in function for such things.</p>
  
  <p>Thanks in advance</p>
