PLMTEX(3plplot)

✨ PLMTEX 💅

okay so bestie, welcome to the plmtex glow-up 🎀 this is a PLplot API page and it's literally about writing text relative to viewport boundaries. no cap, it's giving "label placement but make it fashion" ✨

🌸 NAME 🌸

plmtex — write text relative to viewport boundaries 💖

---

🦋 SYNOPSIS 🦋

plmtex(side, disp, pos, just, text)

---

👑 DESCRIPTION 👑

So the whole vibe here: plmtex writes text at a position you specify, measured relative to the viewport boundaries. Big main character energy. ✨

The text can go inside or outside the viewport — flexible, we love her — but heads up, it gets clipped at the subpage boundaries 😭 so don't try to escape the subpage, she will not let you.

Now the slightly unhinged but important bit: the reference point of a string sits along a line that passes through the string at half the height of a capital letter. That's the landmark, okay? 🎯 The position of that reference point along the line is decided by just, and the position of the reference point relative to the viewport is set by disp and pos. Three little parameters running the whole show 💅

Redacted form: General: plmtex(side, disp, pos, just, text)

Oh and fun fact, this function shows up in examples 3, 4, 6-8, 11, 12, 14, 18, 23, and 26. she's booked and busy fr fr 🔥

🎀 ARGUMENTS 🎀

• side (PLCHAR_VECTOR(3plplot), input) — an ascii character string telling us which side of the viewport the text gets written along. It must be one of these, no improvising:
  • b: bottom of viewport, text written parallel to edge
  • bv: bottom of viewport, text written at right angles to edge
  • l: left of viewport, text written parallel to edge
  • lv: left of viewport, text written at right angles to edge
  • r: right of viewport, text written parallel to edge
  • rv: right of viewport, text written at right angles to edge
  • t: top of viewport, text written parallel to edge
  • tv: top of viewport, text written at right angles to edge
• disp (PLFLT(3plplot), input) — where the string's reference point sits, measured outwards from the viewport edge you picked, in units of the current character height. Pro tip bestie: use a negative disp if you wanna write within the viewport 💜
• pos (PLFLT(3plplot), input) — where the reference point sits along that edge, expressed as a fraction of the length of the edge. slay, proportional placement ✨
• just (PLFLT(3plplot), input) — this one's about the string's position relative to its own reference point. If just=0., the reference point is at the left; if just=1., it's at the right of the string. Any other value of just gives you intermediate justifications — so there's a whole spectrum, she contains multitudes 🦋
• text (PLCHAR_VECTOR(3plplot), input) — a UTF-8 character string that gets written out. give us the content 👑

ngl the one thing to remember: disp goes outwards from the edge (negative = inside), pos slides you along the edge as a fraction, and just decides which bit of the string the reference point is attached to. icon behaviour, honestly 💅
