[Gnuplot-info] rotation center

[Zhong R. <re...@uc...>]

Please consider the following script that draws a sphere.  Why
the rotation center is not at the center of the sphere, when
the graphics is spun by the mouse?  If I change to "set xrange
[ 6 :  44]", the rotation center becomes the center of the
sphere.  This makes the behavior of one of my large
applications unpredictable.  Is there a way to specify the
rotation center?  If not, how is the center selected by Gnuplot?

set terminal x11 0 size 1024,1024
set parametric
set view equal xyz
set xlabel "x"
set ylabel "y"
set zlabel "z"
set xrange [ 6 :  43]
set yrange [80 : 118]
set zrange [13 :  51]
set pm3d implicit at s
splot 10*cos(u)*cos(v)+25,10*cos(u)*sin(v)+99,10*sin(u)+33

Thanks for your help.
