Ah, lost me.  Say what?

Another vote for the new patch.

Yes, easy to change, but looks terrible to me, and everyone I showed
it too.

You said similar on the plot clipping.  Have you looked at the new --clip
option?  Does that look good to you?  Maybe something to tweak.

If you run ntpviz with the new -D 2 option, the plot files then are
left in your system temp directory.  Yuu can then trivially edit them.
Say change 'with lines' to 'with linespoints'.  If you can some up with 
a 'more pleasing' graph I can make it an option.
