snapplotv - display an N-body snapshot file as a vector field
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].
snapplot(1NEMO)
, bodytrans(1NEMO)
, snapshot(5NEMO)
.
There is no autoscaling.
