    Thank You! This works perfectly! I can't say I fully understand 'how' this works, I'm slightly confused as to what is happening in the following lines of code. But thanks once again!

    ' Ajax Control Adding
    Dim cm As ClientScriptManager = Page.ClientScript
    Dim cbReference As String = cm.GetCallbackEventReference(Me, "arg", "ReceiveServerData", "context")
    ' Add Javascript on page
    Dim callbackScript As String = "function CallServer(arg, context)" + "{" + cbReference + "; }"
    cm.RegisterClientScriptBlock(Me.GetType(), "CallServer", callbackScript, True)
    [code]

    I've added a chart to my ASP .NET page, and made the chart a hotspot via the 'clickURL' property. When the user clicks the chart, I want to display a larger version in an AJAX Modal popup. This works fine in IE7, but won't work correctly in IE6. The pop-up appears but says 'No Data to display'. If I then hit F5 (refresh), it works fine (until I post-back then it's back to 'no Data...' and F5 to make it work again). I've pasted some test code below which works fine in IE7, but the above issue in IE6. Is there another way I can achieve this...or am I doing something incorrect? Thanks.

    I added the following to the FusionCharts.js file in order to prevent existing page controls from appearing behind the FusionCharts graph (eg drop-down menu):
    

    this.addParam('wmode', 'transparent');
    

    However, this has had an adverse effect when enabling rotation on a 3d doughnut. Instead of a fluid rotation, the rotation effect is staggered. It looks like it freezes then jumps to the new rotation point (if you know what I mean).

    Are there any charts that calculate control limits for you (UCL & LCL) based on the data sample? Either available in FusionCharts or PowerCharts? I noticed on one of the line graphs in the 'Chart Gallery', upper and lower control limits were highlighted (as trend values). I didn't know if the values were automatically calculated based on the data, or whether I'd need to calculate that and apply the values to the graph.
    

    Thanks.

    I am following the drill-down example using ASP in the evaluation version. In order to call the detail graph, you use the following syntax to set up the links:
    

    strXML = strXML & "<set label='" & ors("FactoryName") & "' value='" & ors2("TotOutput") & "' link='updateChart(" & oRs("FactoryId") & ")'/>"
    

    When calling the 'updateChart' function, I want to pass a date value, so it needs to be quoted. How do I correctly add quotes around the date value without terminating the string? This is what I'm trying to do, but adding the single quotes around the date value terminates the string being built. I've tried various ways of escaping the quotes, like '', /'...etc.
    

    strXML = strXML & "<set label='" & RS("SYS_DATE") & "' color='ABC4D6' value='" & RS("AMOUNT") & "' link='updateChart('5/27/2007')'/>"
