Jon Trowbridge <trow@emccta.com> and I just started on a plot application
called Guppi. It is in C++ and has no DPS, though.. We are primarily
interested in financial-type graphs but are trying to write the code to
support many different kinds so people can add what they need. Probably we
will be working on it only until it reaches the minimum level of
functionality we need, and then it will get more features if other people
want to add them.

I would like to see it connected to the spreadsheet via CORBA, once ORBit
works, so you could dump spreadsheet data into a plot and edit plot data
in the spreadsheet. It would also be nice to share spreadsheet number
formatting functionality; we need this to label the axes.

I would also like to play with DGS and have support for it, however I
don't have time to do so. I imagine it could be implemented as an option,
and the program could query the X server to see if it supports DPS.
It would be cool if someone added this. The way we have classes set up
right now it probably wouldn't be all that hard.

Anyway, we will hopefully have a release ready that does something or
other fairly soon.
