Filling a chart with recordset data in asp
Hello Everybody
It's me again, but this time I have an ASP question for you
I've the following code provided by the msnd service
<%
Dim oChart, c, Categories(5), Vals(5), i, sCaption, nData, nOrg
' Get the input value
nData = Request.QueryString("sOrg"
'When the page loads the first time, set ndata to 5
if len(nData) = 0 then nData = 5
' Generate random categories and values for the chart
' These values can come from some existing data source
for i = 1 to 5
Categories(i) = "Machine" & CStr(i)
Vals(i) = nData * Rnd(100)
next
' Create a Chart Object
Set oChart = CreateObject("OWC.Chart")
Set c = oChart.Constants
' Set the different parameters for the ChartSpace
oChart.Border.Color = c.chColorNone
' Get Organization number and use it to set the Caption
nOrg = nData/5
sCaption = "Current Utilizations for Org"
sCaption = sCaption & CStr(nOrg)
' Add a chart and set parameters for the chart
oChart.Charts.Add
oChart.Charts(0).Type = oChart.Constants.chChartTy
oChart.Charts(0).SeriesCol
oChart.Charts(0).SeriesCol
oChart.Charts(0).SeriesCol
oChart.Charts(0).SeriesCol
oChart.Charts(0).HasLegend
oChart.Charts(0).HasTitle = True
' Get a temporary filename to save chart in that file
sFname = Session("FSO").GetTempName
' Export the chart to the temporary file
oChart.ExportPicture server.MapPath(sFname), "gif", 600, 512
' Create a link to the generated file
Response.Write "<img src='" & sFname & "'>"
' Store the file with its path in the session object for cleanup
Session("sTempFile" & Session("n")) = Server.MapPath(sFname)
' Increment the number of files
Session("n") = Session("n") + 1
%>
The code uses Rnd function to generate random values that are shown in the chart, of course. Also, there is the possibility to fill the chart with data from a recordset or database, but i don't know how can it be. Hope someone knows about that, and can help me with this little issue.
Thanks in advanced

The idea here is that you have a series of categories and values that need to be populated. The code above iterates through your recordset, grabs the values for each pair, and then populates the chart.

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
If you can bind the data to the chart in the manner that farzinm suggests, that would be a much better solution than mine.

Ok
I tried both solutions. First one returned me an error due the size of array related to the index of array. The second one returned me the following error
Microsoft Office Chart 9.0 error '80070057'
The given ADO Recordset must be set to client cursor and must not be forward only reading.
/tesis/chart.asp, line 34
Could you tell me why?
Thanks in advance

Try:
RS.Open sql,oConn,3,3
Fritz the Blank
RS.Open sql,oConn,3,3
Fritz the Blank
Or this:
RS.CursorLocation = 3
RS.Open sql,oConn,3,3
Fritz the Blank
RS.CursorLocation = 3
RS.Open sql,oConn,3,3
Fritz the Blank
yes forgot to mention this before you open your connection
objRS.CursorType = adOpenStatic
objRS.CursorLocation = 3
objRS.CursorType = adOpenStatic
objRS.CursorLocation = 3
where adOpenStatic =3

Fritz thanks a lot, you were as helpful as farzinm. Sorry 'bout the points but EE has no option to divide the points. Thanks, and thanks and thanks a lot. See you soon

Actually they do!
In this case, farzinm provided your solution so it is best that points go to him/her anyway.
Good luck with you project,
