Thanks for the suggestion. I tried ratio -1. That has no effect.
I did some more experimenting with set size and found that
'set size 1,0.5' makes the Z axis half-size, not Y. Apparently
for a 3D plot the second number refers to the Z axis and the
first is applied to both X and Y. 'set size 0.5,1' makes both
X and Y half-size while leaving Z its normal length.
I tried 'set size 1,0.5,1' but gnuplot complains about the
third number.

Please let me know if you have any further suggestions.
