## set lwid

This command, which is available in GrADS version 2.1+, allows the user to define a new line thickness setting with a specified width.

### Syntax

`set lwid thickness width`

The `thickness` argument must be an integer in the range of`13 to 256.` Line thickness settings between 1 and 12 are pre-defined and cannot be changed. The `width` argument must be a real number > 0, but line widths greater than 3.0 are not recommended.

### Usage Notes

The default line widths for `thickness` settings between 1 and 12 are:`0.6, 0.8, 1.0, 1.25, 1.5, 1.75, 2.0, 2.2, 2.4, 2.6, 2.8, 3.0.` The default line width for `thickness` settings greater than 12 is 1.0. The units (pixels or points) will depend on the surface being drawn to.

Once a new thickness setting has been defined, it can be used with any command that controls thickness:`set annot, set clopts, set cthick, set grid, set line, set map, set mpt, set string, set xlopts, set ylopts.` The thickness contols when applied to strings (contour labels, axis labels, etc.) will only take effect when Hershey fonts are in use.

### Example

    set lwid 13 1.6
    set cthick 13
