title: Can i snap Highstock navigator extremes to existing points?
body: <p>I'm looking for a way to snap the users min and max extremes to existing points when they use the navigator slider. Is this something i can accomplish with existing options or has anyone else accomplished this? The ultimate goal here would be if i set two points in a series, for example (1365444905, 1) and (1365444919, 10) when the user slides the bar i should only ever get back 1365444905 or 1365444919.</p>
  
  <p>Thanks. </p>
