    Hi Joe,

    I assume you are talking about the "type=topConnections" option? You
    want top connections by bytes?

    The applet parameter for this is "resultSort=bytes", but the MultiChart
    servlet does not detect and pass this parameter through to the applets
    (yet).

    The solution is therefore as follows:

    1. Use MultiChart to get the topConnections chart layout that you want.

    2. Save the html page to disk.

    3. Edit the page to add the following line near the top:
            <base href="http://www.inmon.com/its/query/"></base>
    (substitute your own server for www.inmon.com here).

    4. For each of the applets, you will see a line:
            <param name="type" value="topConnections">
    Just below it, add a new line:
            <param name="resultSort" value="bytes">

    5. Point your browser at this file.

    regards,
    neil
