ASP.net AjaxToolKit LineChart Drawing Series <p>I have the following SqlServer Data Table :<br/><br/>
Years | Sales(A) | Sales(B)<br/>
------------------------------<br/>
2000 | 38000 | 55000<br/>
2001 | 18000 | 47000<br/>
2002 | 70000 | 16000<br/>
2003 | 21000 | 55000<br/>
2004 | 77000 | 5000... | <p>My theory, is the array is just getting appended. *Note, we may need separate arrays as it's getting rendered after the code.</p>

<pre><code> dt = GetData("SELECT Years,A, B FROM LineChart")
y = New Decimal(dt.Rows.Count - 1) {}
y2 = New Decimal(dt.Rows.Count - 1) {}
