Name
sma — Spline map
Syntax
sma i | v | s | n | ms | l | auto | cur [arg1] ;# general syntax for contouring with colorbands, see argument list

Description
Contour lines are drawn using spline curves to achieve smooth contours.

Examples
Ex.1: Spline mapping
# 3d annotation is very different from 2d annotation. z ;# erase display win 450000 460000 6450000 6460000 1500 3000 ; # get a new window by coordinates mak ran 12 ;# make random points grp 110 110 ;# make grid bol tub ;# draw border line n tube mode acm i 250 ;# color band contours spe col con bla blu ;# contour colors are black and blue spe col ann bla ;# annotation color is black sma i 50 csh 250 ann anl shf shliw 3 frq 0.9 ans 1.5; # spline map with annotation
The above example produces this image (somewhat zoomed) using the random generated grid in active data as input.
