GSET_LINEWIDTH(3NCARG)

💅 GSET_LINEWIDTH — it's giving thick line energy ✨

okay bestie, welcome to gset_linewidth(3NCARG), a little NCAR GRAPHICS gem that lives in the NCAR GRAPHICS manual. it's the function that sets the linewidth scale factor — aka the relative thickness of a polyline. yes, we're talking about making your lines THICC. 🫶

🌸 NAME 🌸

gset_linewidth (Set linewidth scale factor) — sets the linewidth scale factor, or relative thickness of a polyline. no cap, that's literally the whole job and it does it beautifully. 💖

✨ SYNOPSIS ✨

#include <ncarg/gks.h>

void gset_linewidth(Gdouble linewidth);

look at that signature. clean. iconic. Gdouble, one arg, no drama. 😌

🎀 DESCRIPTION 🎀

• linewidth (Input) — a scale factor that controls the linewidth of the polyline you're about to draw. it must be greater than or equal to 0. so like, 0 is fine, negative is not the vibe. 🚫

linewidth gets applied to the nominal linewidth on whatever device you're on, and then — plot twist — the linewidths are mapped to the nearest available linewidth representable on that device. so basically your device has a little menu of thicknesses it can actually do, and it rounds you to the closest one. it's giving "we'll get as close as we can, bestie." 🙈

by default linewidth = 1.0, so setting linewidth = 2.0 will double line width on most devices. double it. slay. 🔥

🦋 ACCESS 🦋

to use the GKS C-binding routines, you gotta load the ncarg_gks and ncarg_c libraries. that's the entry fee, babes. 💜
