PLERRX(3plplot)

💖 PLERRX 💖

okay so real talk, you're looking at the PLplot API page for plerrx, bestie. that's the whole vibe. let's go 🫶

---

✨ NAME ✨

plerrx — draws error bars in the x direction, and honestly? iconic behavior. 💅

---

🌸 SYNOPSIS 🌸

plerrx(n, xmin, xmax, y)

---

🦋 DESCRIPTION 🦋

so what this does is draw a whole set of n error bars going in the x direction, and the i'th one stretches all the way from xmin[i] to xmax[i], sitting at the y coordinate y[i]. literally that's it, that's the whole thing. ✨

and the little end caps on the error bars? the terminals? they're the same length as the minor tick length — which you can set with plsmin(3plplot). so if you want them chunkier or tinier, that's your knob, iykyk. 🎀

Redacted form: General: plerrx(xmin, ymax, y)

(no cap, that's the redacted form, just like it says — ymax and all 🙈)

this function is used in example 29. go look at it, it slays. 🔥

👑 ARGUMENTS 👑

• n (PLINT(3plplot), input) — the number of error bars to draw. how many?? you decide. main character choice. 💫
• xmin (PLFLT_VECTOR(3plplot), input) — a vector holding the x coordinates of the left-hand endpoints of the error bars. the lefties. 💜
• xmax (PLFLT_VECTOR(3plplot), input) — a vector holding the x coordinates of the right-hand endpoints of the error bars. the righties. 🌈
• y (PLFLT_VECTOR(3plplot), input) — a vector holding the y coordinates of the error bars, aka where they actually live vertically. ⭐
