plvec0: Vector plot, identity mapping for Fortran 77

plvec0 (u, v, nx, ny, scale);

Draws a vector plot of the data in (u[nx][ny], v[nx][ny]).

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 u and v.

scale (PLFLT, input)

Parameter to control the scaling factor of the vectors for plotting. If scale = 0 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. If scale > 0 then the scaling factor is set to scale.

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.
