Latest release (1.9.13) supports large sheets provided your computer has enough memory. The sheets size can be changed at runtume, so you don't need a recompilation anymore. You can have up to 16M rows, so it will be enough for your needs. Just I don't really know how fast gnumeric is with very large sheets. Of course, 1.9.13 is a devalopment version, but it seems fairly stable, and we should have the next stable (1.10.0) within three months or so. > Secondly, users will query the database via a web form, which, once > submitted, produce a variety of graphs.

Formats available for axis labels are the same that you can have in a sheet cell. Recently there were some enhancements for axis labelled as dates, so I suppose it should work for you. > Of course the functionality I'm searching for would likely be more > readily found in a database app, like MySQL, but I've been using > gnumeric for a long time (though not its graphing capabilities), so am > more comfortable with it.
