Let's go back to the top.
You ask about panning in 3D.  There is no built-in hotkey or mouse action
for this, but you can define it yourself as follows.

Set up the hot keys:

  delx = 0
  dely = 0
  delz = 0
  bind x "delx = delx+1; replot;"
  bind y "dely = dely+1; replot;"
  bind z "delz = delz+1; replot;"
  bind X "delx = delx-1; replot;"
  bind Y "dely = dely-1; replot;"
  bind Z "delz = delz-1; replot;"

Now plot your data set through the defined offsets.
The gnuplot demo set doesn't include a sample propellor blade,
but it does have a whale.  Let's use that.

  set border -1
  set xr [-10:10]; set yr [-5:5]; set zr [-2:2]
  splot 'whale.dat' using ($1+delx):($2+dely):($3+delz)

Your screen should now contain a box with a whale in it.
The hotkeys x/X y/Y z/Z will displace the whale within the fixed box.

You could similarly add a scale factor hooked up to another pair
of hotkeys, applied before or after the offset according to taste.

	happy whale navigation,

		Ethan
