Well i've come up with an easy solution to the updatepanel problem.

There is a free flash control on http://www.flash-control.net/

Protected Sub CreateChart()
Dim QueryString As String = String.Format("../xml/GetAccountsXml.aspx?UserName={0}&QueryType={1}", User.Identity.Name, GraphType.SelectedValue)
Dim dataURL As String = InfoSoftGlobal.FusionCharts.EncodeDataURL(QueryString, True)
Me.FlashControl1.Height = 350
Me.FlashControl1.Width = 900
Me.FlashControl1.BorderColor = Drawing.Color.WhiteSmoke
Me.FlashControl1.BackColor = Drawing.Color.WhiteSmoke
Me.FlashControl1.Menu = False
Me.FlashControl1.MovieUrl = "../FusionCharts/Line.swf"
Me.FlashControl1.SwLiveConnect = True
Me.FlashControl1.FlashVars = String.Format("&chartWidth={0}&chartHeight={1}&debugMode={2}&dataURL={3}", 900, 350, 0, dataURL)
End Sub

This is working brilliantly for me, plus it is free.

The only minor glitch is that it has that whole "click to activate thing" happening (control must be using html to render the chart)

I'd still prefer to use a official FusionChart control, but hey time is money and i've spent enough time on this problem already.

Hope you have fun.
