Name

snapplotv - display an N-body snapshot file as a vector field

Synopsis

snapplot in=snap-file [parameter=value] ...

Description

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.

Parameters

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].
