GPOLYLINE(3NCARG)

💖 GPOLYLINE 💖

okay bestie, welcome to GPOLYLINE from the NCAR GRAPHICS family (manual page GPOLYLINE(3NCARG), iykyk). This one's a little output primitive, and its whole vibe is: draw line segments connecting a sequence of coordinate pairs that you the user specified. that's it, that's the job. slay ✨

---

✨ NAME ✨

gpolyline (aka Polyline) — this output primitive draws line segments connecting a sequence of user-specified coordinate pairs. literally just connect-the-dots but make it graphics 💅

---

🎀 SYNOPSIS 🎀

#include <ncarg/gks.h>

void gpolyline(const Gpoint_list *point_list);

---

🦋 DESCRIPTION 🦋

so here's what you're working with, bestie:

• point_list.num_points — (Gint, Input) — the number of points in the line you wanna draw. it must be larger than one, no cap. one point is not a line, it's a cry for help 😭
• point_list.points — (Gint *, Input) — the X and Y coordinates (specified in world coordinates) of the point_list.num_points points that are gonna get connected by line segments.

---

💜 USAGE 💜

okay this part matters so listen up 🫶 — those coordinate pairs must be in world coordinates and not user coordinates. and like, among other things, this means the log scaling and mirror-imaging features you can get via the c_set call, plus the SPPS functions for drawing lines, are not applicable here. so don't come for them, they don't work in this context. periodt.

🌸 ACCESS 🌸

to use the GKS C-binding routines, load the ncarg_gks and ncarg_c libraries. that's the whole thing, bestie, go forth and link 🔥
