Do While Populate Graph

Latitude7ds

from: somewhere When using variables like the comented line under add data I get an error stating object reference not set. Use 'GetGraph'. I have tried various methods to induce variables into the Call. It seems to only accept static text like the un-comented line under add data.

<%
If Not Subrst.EOF and Not Subrst.BOF Then
Subrst.movefirst
Do While Not Subrst.EOF

'Add data
'Call objGraph.AddRowData(Subrst("ProductName"),Subrst("Weight"))
Call objGraph.AddRowData("Kevin Garnett","35,40")
Subrst.movenext
Loop
With ObjGraph
'Add some variables
objGraph.XScaleValues = "Product"
objGraph.xALign = "center"
objGraph.yLabel = "Weight"
objGraph.Title = "Product Weights"
End With
objGraph.Draw
End If
%>

Also: your links in SimpleGraph Object Referance do not work.

The GetGraph function just returns the graph as an HTML text string.
Make sure that you do not add any NULL values in to the graph. I will forward this bug.
However, try this:

<%

  If objRS.EOF  Then
     'no records returned
  Else
     Do  While Not objRS.EOF
         Call objGraph.AddRowData(objRS("ProductName") & "",  _
             ParseDbl(objRS("Weight") & ""))
        objRS.MoveNext
     Loop
     objRS.Close

     With ObjGraph
          'Add some variables
          objGraph.XScaleValues = "Product"
          objGraph.xALign = "center"
          objGraph.yLabel = "Weight"
          objGraph.Title = "Product Weights"
     End  With
     objGraph.Draw
    'or
    'Response.Write(objGraph.GetGraph)
  End  If

  Function ParseDbl(ByVal s)
     If  IsNumeric(s)  Then ParseDbl=CDbl(s)  Else ParseDbl=0
  End  Function

%>
