As far as I know there's no way to show any other documents than QVW in the Accesspoint webpage. If you browse for the server files, you may find some JS file that allows you to list different files, but as far as it's not the intention of the Accesspoint, it's unlikely.
Rather, what I'd do is to create an application that shows within a chart the list of PDF documents in your folders.
Search the forum for DoDir and you will find some useful macros and script codes you can use for that.
Hope that helps.
