Solution 1

It all depends on what you mean by 'not working'.
Maybe you just need to treat Y values as double, instead of string?

C#

foreach (DataRow r in initialDataSource.Rows)
{
   series.Points.AddXY("Actual", double.Parse(r["Actual"].ToString()));
   series.Points.AddXY("unavailable_actual", double.Parse(r["unavailable_actual"].ToString()));
   series.Points.AddXY("budget", double.Parse(r["budget"].ToString()));

   // ...
}

The X value needs to be a double as well; "Actual", "unavailable_actual", and "budget" are not valid X values. :)

That puzzled me too, what I proposed is just a long, long shot. Under this form, I guess the AddXY(Object, Object[]) overload will be used.
The meaning of 'not working' should really be detailed.
