That's not really an appropriate use of @onlyreplace.  Just put the
chart and table in <iframe>s with @name and use <a target> to refresh
them.  That also automatically optimizes bandwidth, since the subpages
that the chart and frame will live on contain *only* them.

(Preventing this sort of abuse might be a good reason to do the "only
<base> can carry an id list" revision.)
