title: Add additional data to point using DotNet.Highcharts
body: <p>I am learning how to use HighCharts with Visual Studio.  I am using DotNet.Highcharts to hopfully make it easier.  I have a series with the y value of totalAttempts which is and integer and the x value of DateTime.  The series is a spline chart.  I would like to add additional data.  </p>
  
  <p>How can I add additional data to each point using DotNet.Highcharts?</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>I have a Series List that I use to add all of the needed Series to:</p>
  
  <pre><code>List&lt;Series&gt; mySeries = new List&lt;Series&gt;();
  </code></pre>
  
  <p>I use an array list to hold each of the data points needed    </p>
  
  <pre><code>var myResults = new List&lt;object[]&gt;();
  </code></pre>
  
  <p>Then I loop through the results of a query several time to gather the data for each point of a Series.  Here is the code I use:</p>
  
  <pre><code>myResults.Add(new object[] 
  { 
          detailRecords.groupedDate, //represents x
          detailRecords.totalAttempts //represents y
  });
  </code></pre>
  
  <p>Then after the data points are all created, I then add the array list as the data for a Series</p>
  
  <pre><code>mySeries.Add(new Series
  {
      Name = mainRecords.name,
      Data = new Data(myResults.ToArray())
  });
  </code></pre>
  
  <p>What I don't know how to do is add additional information to the data points so I can display it when it is hovered over.  The question <a href="https://stackoverflow.com/questions/8514457/set-additional-data-to-highcharts-series">Set Additional Data to highcharts series</a> shows how to do this but I can't seem to get it working with DotNet.Highcharts.</p>
