PLPSTY(3plplot)

💅 PLPSTY(3plplot) — like, the area fill pattern selector, bestie

okay so this is a page from the PLplot API manual and it's literally all about plpsty, which picks your area fill pattern. yes. patterns. for filling areas. we love a glow-up for your plots 🎀

---

✨ SYNOPSIS ✨

plpsty(patt)

that's it. one argument. she's low maintenance. 💅

---

🌸 DESCRIPTION 🌸

so here's the vibe check on patt:

• if patt is zero or less, you get a hardware solid fill — but only if the drivers have that capability (and honestly, virtually all of them do 🫶). If they don't, no worries, it falls back to a software emulation of a solid fill using the eighth area line fill pattern. cute of her, honestly.
• if 0 < patt <= 8, you're selecting one of eight predefined area line fill patterns. that's the whole menu. and if you want something else? go see plpat(3plplot) — she has options. 😭

Redacted form: plpsty(patt)

and iykyk, this function shows up in examples 12, 13, 15, 16, and 25 — so go look at those if you want to see her in action. 👑

🦋 ARGUMENTS 🦋

• patt (PLINT(3plplot), input) — the desired pattern index, bestie. if patt is zero or less, then a solid fill is used (normally, see the qualifiers above — don't come for me, that's what the docs say 🙈).

now for the good part: for patt in the range from 1 to 8, and assuming the driver hasn't supplied line fill capability itself (and most of them deliberately do not, so that line fill patterns look identical for those drivers — consistency queen 💖), the patterns are:

1. horizontal lines
2. vertical lines
3. lines at 45 degrees
4. lines at -45 degrees
5. lines at 30 degrees
6. lines at -30 degrees
7. both vertical and horizontal lines
8. lines at both 45 degrees and -45 degrees

so like, literally pick a number between 1 and 8 and get a whole new aesthetic. slay. 🔥

reminder bestie: patterns 1–8 only, and anything zero or less is solid fill. don't try to get fancy with patt = 9 unless you're ready to call plpat(3plplot) instead. 🎀
