**Line Graphics Scalar File Format.**

This file contains the values of the computed scalar fields. The header file defines the number of data points in this file.

The file must contain `nxyfs` rows and `nfs` columns.
The precise format of each piece of data is not critical,
but the ordering of the data is critical. The file format is as follows.

s1(i*h,j*h) s2(i*h,j*h) ... s1(i*h+h,j*h) s2(i*h+h,j*h) ... ...

**Notes:**

- 1.
- Each column corresponds to a scalar field. The first number in each
row is the first scalar field, the second number is the second scalar
field and so on.
- 2.
- Each rows corresponds to a point in the domain where the scalar
fields are computed. The data are listed row-wise (left to right)
from the bottom to the top. Therefore, the first
`nx`rows are the scalars along the bottom row (*y*=ymin and*x*=*i***h*, where`nx`). The next`nx`scalars correspond to the second row (*y*=ymin+h and*x*=*i***h*, where where`nx`), and so on. The last`nx`vectors correspond to the final row.
