DESCRIPTION

The CSV file format is used by the vfplot (1) program for representing vector fields defined on a grid.

The format is simply CSV, with two columns of integer indices (indicating location on the grid) and two for floating-point components of the vector at that location.

Note that when using such files as input for vfplot (1) , one would typically use the --grid-range and --grid-size options.

EXAMPLE

The following file describes a 3x3 grid of two dimensional vectors.

0, 0, 3.0, 3.0
0, 1, 1.2, 3.2
1, 1, 2.3, 3.2
2, 1, 1.7, 5.1
2, 2, 1.1, 3.2

and typical options --grid-size 3/3 and --grid-range 0/1/0/1.
