QwtIntervalData(3)

✨ QwtIntervalData ✨

okay bestie, welcome to the QwtIntervalData page from the Qwt User's Guide 💖 this one's a little cutie — she's a data holder, she holds samples, and she's lowkey the reason your error bars and histograms look so good. let's get into it 🫶

🌸 NAME 🌸

QwtIntervalData — no further description on the page, she's mysterious like that 💅

💜 Detailed Description 💜

Series of samples of a value and an interval. 🌈

okay so here's the tea ☕ QwtIntervalData is literally a series of samples of a value and an interval. that's the whole vibe. fr fr.

for example — error bars are built from samples [x, y1-y2], while a histogram might consist of [x1-x2, y] samples. see how the interval and the value just swap places depending on what you're building? iconic behavior honestly 👑

🦋 Member Function Documentation 🦋

QwtDoubleRect QwtIntervalData::boundingRect () const

Calculate the bounding rectangle of the samples ✨

the x coordinates of the rectangle are built from the intervals, the y coordinates from the values. she's mixing and matching and honestly? slay.

Returns:

• Bounding rectangle 💖

---

const QwtDoubleInterval & QwtIntervalData::interval (size_ti) const [inline]

Interval of a sample 🎀

Parameters:

• i — Sample index

Returns:

• Interval

See also:

• value(), size()

ngl the page literally spells that parameter size_ti right here — not me fixing it, i'm just the messenger 🙈

---

size_t QwtIntervalData::size () const [inline]

Returns:

• Number of samples 🔢

that's it. that's the whole function. short queen, she ate 💅

---

double QwtIntervalData::value (size_ti) const [inline]

Value of a sample... okay Value of a sample 🌸

Parameters:

• i — Sample index

Returns:

• Value

See also:

• interval(), size()

and yeah, this one says size_ti too. keeping it exactly as the page has it, no cap 🫡

⭐ Sign-off ⭐

this was Version 5.2.3, dated Tue Nov 20 2012 — and that's the whole page bestie, every option, every signature, every [inline], all of it intact 🎀 you understood the assignment, now go build those error bars 💖🦋✨
