ncl_gset_char_space man page
gset_char_space (Set character spacing) — sets the character spacing for text.
void gset_char_space(Gdouble char_space);
(Input) - Specifies how much additional white space should be inserted between characters drawn using the gtext output primitive. char_space is specified as a fraction of the character height.
A character spacing of zero positions the character body of each successive character contiguously with enough white space between them to produce pleasing normal spacing. A positive value inserts extra space between successive characters. A negative value causes successive characters to overlap. By default char_space = 0.0.
To use the GKS C-binding routines, load the ncarg_gks and ncarg_c libraries.
