snapplotv - display an N-body snapshot file as a vector field (quiver
plot)
snapplot in=snap-file [parameter=value] ...
snapplotv
is derived from snapplot(1NEMO)
, i.e. plots a standard N-body snapshot file
on a selected graphics device, but in addition two bodytrans(1NEMO)
variables
are selected that respresent a vector field.
The following additional
parameters to snapplot have been defined:
- vxvar=vx-expression
- The value
of vx-expression is plotted determines the length of the vector along the
X axis. vx-expression is a real-valued C language expression over the real
values x, y, z, vx, vy, vz, phi, t, and the integer value i. The default
is vx.
- vyvar=y-expression
- See above. The default is vy.
- scale=factor
- The factor
with which each vector is multiplied to make unit velocity come out as
1/20 (1cm for yapp) of the plot. [Default is 1].

There is no autoscaling.
