💖 QwtCurveFitter(3) 💖

okay bestie, welcome to the Qwt User's Guide, section 3 — sit down, hydrate, and let's talk about QwtCurveFitter.

✨ NAME ✨

QwtCurveFitter — and that's it. that's the whole description. the manpage literally leaves it blank after the dash 💀 iconic minimalism honestly, she said "my work speaks for itself" and dipped.

🎀 SYNOPSIS 🎀

#include <qwt_curve_fitter.h>

Inherited by QwtSplineCurveFitter.

so like, QwtSplineCurveFitter is her daughter, her protégé, her main character successor 🫶

👑 Public Member Functions 👑

• virtual ~QwtCurveFitter () — the destructor, virtual so everyone gets properly cleaned up, no messy breakups 💅
• virtual QPolygonF fitCurve (const QPolygonF &polygon) const =0 — the big one. pure virtual, meaning you have to implement it, she's not doing it for you, bestie 🌸

---

🔒 Protected Member Functions 🔒

• QwtCurveFitter () — the constructor, protected, so nobody can just casually make one of her. she's abstract, she's mysterious, she's giving untouchable 🦋

---

💜 Detailed Description 💜

Abstract base class for a curve fitter.

that's the vibe. she's the blueprint, the template, the "you can't sit with us unless you inherit from us" energy. no cap, you don't instantiate her — you become her, through inheritance ✨

🧚 Member Function Documentation 🧚

virtual QPolygonF QwtCurveFitter::fitCurve (const QPolygonF &polygon) const

[pure virtual] — yes, the brackets are part of the lore. she's abstract, she's a promise, she's not implemented here.

Find a curve which has the best fit to a series of data points

like, take all your messy little points and find the glow-up curve that fits them best. it's giving matchmaker but for geometry 💖

Parameters:

• polygon — Series of data points. (your raw, unglamorous input 🍓)

Returns:

• Curve points. (the gorgeous fitted result ✨)

Implemented in QwtSplineCurveFitter.

so if you want to actually see this working, go knock on QwtSplineCurveFitter's door. she did the homework. she ate and left no crumbs 🔥

no human author, no moodboard, no notes — just Doxygen doing her little autogenerated thing. we respect the process 🙈

lowkey a warning: she's an abstract base class and fitCurve is pure virtual — you literally cannot instantiate QwtCurveFitter and you cannot call fitCurve on her directly. subclass her or go home, periodt 💀

Version 5.2.3 — Tue Nov 20 2012

and that's the whole page bestie, mwah 💋 stay abstract, stay iconic, and remember: if it's pure virtual, it's not on you to implement it — it's on your subclass. slay 👑💅🦋
