Add additional data to point using DotNet.Highcharts

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. How can I add additional data to each point using DotNet.Highcharts? UPDATE I have a Series List that I use to add all of the needed Series to: ``` List<Series> mySeries = new List<Series>(); ``` I use an array list to hold each of the data points needed ``` var myResults = new List<object[]>(); ``` 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: ``` myResults.Add(new object[] { detailRecords.groupedDate, //represents x detailRecords.totalAttempts //represents y }); ``` Then after the data points are all created, I then add the array list as the data for a Series ``` mySeries.Add(new Series { Name = mainRecords.name, Data = new Data(myResults.ToArray()) }); ``` 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 Set Additional Data to highcharts series shows how to do this but I can't seem to get it working with DotNet.Highcharts.
