💅 PLSDIDEV 💅 (that's plsdidev from the PLplot API, bestie)

okay so real talk, this is a page from the PLplot API manual and it's all about plsdidev — the little function that sets up your device-space window vibe. let's get into it ✨

✨ NAME ✨

plsdidev — Set parameters that define current device-space window 🎀

🦋 SYNOPSIS 🦋

plsdidev(mar, aspect, jx, jy)

🌸 DESCRIPTION 🌸

so basically this one sets the relative margin width, the aspect ratio, and the relative justification — and those three things together are what define your current device-space window. window math, but make it fashion 💅

here's the tea tho: if you wanna just keep whatever value was already there for any of these, you literally just pass in the magic value PL_NOTSET and it's like "say less, we got it" ✨

ngl it's unlikely you'd ever actually need to change the aspect ratio, but it's in there for completeness. it ate, it's thorough, we respect it 🫶

and important: if plsdidev(3plplot) never gets called at all, the default values of mar, jx, and jy are all 0. meanwhile aspect is set to a device-specific value (iykyk, it's different per device).

Redacted form: plsdidev(mar, aspect, jx, jy)

oh and fun fact: this function is used in example 31 👑

💖 ARGUMENTS 💖

  • mar (PLFLT(3plplot), input) — the relative margin width 🍓
  • aspect (PLFLT(3plplot), input) — the aspect ratio 📐
  • jx (PLFLT(3plplot), input) — relative justification in x. the value must lie in the range -0.5 to 0.5 ⭐
  • jy (PLFLT(3plplot), input) — relative justification in y. the value must lie in the range -0.5 to 0.5 ⭐
respectfully, don't go outside those ranges on jx and jy — the docs said what they said 🙈
