I used to use CoPilot on a *Palm* and it was exactly what I am now
after, but the HP4700 is Pocket/PC.

Alas and alak.

If it can run excel, you can dummy one up pretty quickly. There is one
at http://www.flying20club.org. At the top, click on "our aircraft",
then at the bottom of that prose, click on any of the actual aircraft.
There are "bring up spreadsheet" links I've set up for our aircraft.
The "new style" one has the graph.

You are welcome to use them as templates, download the spreadsheet and
update it with your own aircraft info, and TEST it. The lawyers are
going to make me emphasize that it is YOUR responsibility to ensure that
your W&B is correct, and that this spreadsheet implies no legal
obligation or liability on our part.

But you knew that.
