I think that some kind of compromise will be necessary.  

Like the tables, the plots need to have better seperation between 
data and presentation.

For example, the only way that the current system can possibly put
graphs in the odt output, is as monolithic images.  This is fine so
far as it goes, but I expect users would prefer to have them as
ODF native graphs, so that the presentation can be changed to suit
the whim of the user (eg: change colours, scales, label fonts etc).

From what I remember of the way I implemented the NP plots in the examine
command, it's rather kludgy (perhaps Ben has improved it in the output
branch), which is one reason why I didn't attempt to re-use any of that
code for the roc command, even though they logically should do so.

     a team of developers willing to work about full time to implement the
     system, it would be better for us just to write graphical routines in
     a more straightforward way. Which I guess means we can keep using the
     routines we already have?
