title: How to set xAxis minimum and maximum values on Highstock?
body: <p>I have a little problem with my HighStock Charts. I am plotting data from a database which returns speed values of a car in a certain period of time (3 days).</p>
  
  <p>For example, I want to plot the speed values between 1st January at 00:00 and 3rd January at 00:00, but I just have values on the 2nd of January...the other days the car was parked. </p>
  
  <p>What is happening is that highstock auto adapts the xAxis for period where there is available data, in this case 2nd January...it doesn´t show me the other 2 days where the car was parked.
  Is there a way to set a fixed start date and end date on xAxis? I've tried to find something in the documentation but so far nothing worked.</p>
  
  <p>Could you help me?</p>
  
  <p>Thanks in advance</p>
