After applying Group By to an IR, no further formatting can be performed

Question

I have an interactive report that shows multiple accounts across many dates. I would like to create a chart by date for the total of all accounts.
As soon as I apply the format of Group By, the format menu is no longer available so I can't chart it.
Is it possible to do this?

Timo,
I don't know, nor can I find the relevent bug in metalink. Can anyone at Oracle tell us?
In my opinion, the best solution would be to apply the row limit to the outer part of a group by (or chart) query. In can't imagine a use case where anyone would want to perform a group by on an (effectively random) subset of the available data.
The problem I have is that I have a couple of IR's on two very large tables (around 1M rows each). When the reports are showing each record, I'd like to apply the row limit (to say 10,000 rows are less), but when they are showing chart or group by results, I want to show this based off all the available data (although it would be ok / good to have the row limit applied outside the group by).
At the moment I'm looking for a workaround, the best I can see would be to put a rowlimit clause in the IR query and base that on a page item, then setting the page item based on the report display type (report / group by / chart). I'm not sure how to get a javascript to fire when the report is updated though.
