(u, v, nx, ny, scale, xg, yg);
Draws a vector plot of the data in
(PLFLT **, input)
Pointer to a pair of vectored two-dimensional arrays containing
the x and y components of the vector to be plotted.
Physical dimensions of the arrays
Parameter to control the scaling factor of the vectors for plotting.
scale = 0 then
the scaling factor is automatically calculated for the data.
scale < 0 then
the scaling factor is automatically calculated for the data and
then multiplied by -
scale > 0 then
the scaling factor is set to
(PLFLT *, input)
Pointers to arrays which specify the transformation from array
indices to world coordinates. These must be two-dimensional
arrays, used for a transformation of the form:
tx = f(x, y),
ty = f(x, y). Function
values at locations between grid points are obtained via linear
NOTE: this function is intended for use from a Fortran 77 caller only.
The C user should instead call
plvect using the built-in
pltr2 for the same
