TDGRID(3NCARG)

✨ TDGRID — it's giving grid lines, bestie ✨

okay so this is a page from the NCAR GRAPHICS manual, and the routine is TDGRID. 🎀

---

💖 NAME 💖

TDGRID — draws a perimeter around the edges of the reference parallelogram that was defined by the last call to TDPARA, and you can optionally get ticks or grid lines too. 🦋

Real talk: this routine is normally called indirectly (basically, TDGRDS calls it for you), but there is literally no reason why you couldn't call it directly. She's independent, she's self-sufficient. 👑

---

🌸 SYNOPSIS 🌸

CALL TDGRID (XBEG, XSTP, NOXS, YBEG, YSTP, NOYS, IGRD)

---

🌈 C-BINDING SYNOPSIS 🌈

#include <ncarg/ncargC.h>

void c_tdgrid(float xbeg, float xstp, int noxs, float ybeg, float ystp,
int noys, int igrd)

---

✨ DESCRIPTION ✨

The arguments of TDGRID are giving very much "here's what you're passing in, bestie": 💅

• XBEG, XSTP, and NOXS — these are input expressions of types REAL, REAL, and INTEGER, respectively. They define where the ticks or grid lines get drawn along the "X" axis of the parallelogram — specifically at XBEG, XBEG+XSTP, XBEG+2*XSTP, ... XBEG+NOXS*XSTP. 🧚
• YBEG, YSTP, and NOYS — again, input expressions of types REAL, REAL, and INTEGER. These define where ticks or grid lines get drawn along the "Y" axis of the parallelogram — at YBEG, YBEG+YSTP, YBEG+2*YSTP, ... YBEG+NOYS*YSTP. 💜
• IGRD — an input expression of type INTEGER, and she decides what actually gets drawn. She takes one of these three values:
  • 1 — draw just a perimeter. minimal. clean. 🎀
  • 2 — draw a perimeter with inward-pointing ticks. 🔥
  • 3 — draw a perimeter with a grid. slay. 👑

🫶 C-BINDING DESCRIPTION 🫶

The C-binding argument descriptions are the same as the FORTRAN argument descriptions. no cap, they did not change a single thing. 😭

---

⭐ ACCESS ⭐

To use TDGRID or c_tdgrid, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c — preferably in that order. fr fr, order matters here. 💖

⚠️ heads up bestie: that license agreement line is not a vibe, it's a rule. respect it. 🙈

okay and one last thing — this whole page is a UNIX manual page, dated July 1997, and it lives at TDGRID(3NCARG). so if you ever need to cite her, that's the glow-up receipt. 💅✨ bye ily, go draw a parallelogram 🫶💜
