Re: Real Time Charting on XY chart type

[User (Legacy)]

Ok, then I have a follow up question....

Is there an easy way to reference an existing chart on the server.  Or in

other words is there a way to get at the "DATAPATH" value that is generated

in the HTML when a chart is produced.

That is, is there a way to somehow collect the DATAPATH value that is

generated when I call

    Response.Write( cfxECI.GetHtmlTag("100%","96%"))

And then put the DATAPATH string into a session variable for use by other

pages or the same page after a resubmit ?

If I knew the DATAPATH value then I could write the following HTML via ASP

code and produce the chart again (without re-querying).

<OBJECT

    CLASSID="CLSID:21F49842-BFA9-11d2-A89C-00104B62BDDA"

    TYPE="application/x-oleobject"

    WIDTH="100%"

    HEIGHT="96%"

    ID="Chart1"

    CODEBASE=/download/CfxIEAx.cab#Version=4,5,18,1>

<PARAM NAME="LICENSE" VALUE="/license/CfxIE.lic">

<PARAM NAME="DATAPATH" VALUE="/cfxtemp/CFT0112_123310290.chw">

</OBJECT>

This technique would allow me to periodically resubmit an asp page that

looks for new records AND then only requery the chart if there are new

records.  If there are no new records, just re-present the existing chart

that is already on the server.
