u, v
(PLFLT **
, input)
Pointer to a pair of vectored two-dimensional arrays containing the x and y components of the vector to be plotted.
nx, ny
(PLINT
, input)
Physical dimensions of the arrays
and
u
.
v
scale
(PLFLT
, input)
Parameter to control the scaling factor of the vectors for plotting.
If
then
the scaling factor is automatically calculated for the data.
If scale
= 0
then
the scaling factor is automatically calculated for the data and
then multiplied by scale
< 0-
.
If scale
then
the scaling factor is set to scale
> 0

NOTE: this function is intended for use from a Fortran 77 caller only.
The C user should instead call plvect
using the built-in
transformation function pltr0
for the same
capability.
