title: How to display only last data point on highcharts?
body: <p>I have a multiple line chart that will be dynamically updated every day (or more). I know the start and end dates (it will last 2 months). </p>
  
  <p>I want to display only the point of the last data entry but not the older ones. Basically, I want my series to look like this : <a href="http://jsfiddle.net/jlbriggs/JVNjs/281/" rel="nofollow">http://jsfiddle.net/jlbriggs/JVNjs/281/</a> </p>
  
  <p><code>data: [7,12,16,32,{y:64,marker:{enabled:true,radius:5,fillColor:'#c00'}}]</code></p>
  
  <p>or more accurately, like this: <a href="http://i.stack.imgur.com/FpQF1.jpg" rel="nofollow">http://i.stack.imgur.com/FpQF1.jpg</a></p>
  
  <p>Problem is that my chart updates several time during the day. So I want to display the last updated data on the right day AND to display only the last point. I've tried to select the series' last data by using "lenght - 1" but it didn't work since I'm no expert on JS.</p>
  
  <p>Is there a way to do that ?
  Thanks and ask for better explanations if needed. I'm not sur I was quite clear.</p>
