💖 QwtLinearScaleEngine 💖

okay so this page is straight out of the Qwt User's Guide, and it's all about QwtLinearScaleEngine — the little icon that makes your linear scales behave. no cap, it's short but it's doing a lot. 🫶

✨ NAME ✨

QwtLinearScaleEngine — and that's literally it, bestie, the description line is blank. the class name IS the whole vibe. 💅

🦋 SYNOPSIS 🦋

#include <qwt_scale_engine.h>

Inherits QwtScaleEngine. so it's got the whole family tree behind it, iykyk 🌈

everything else it got from its parent lives here — that's the inherited stuff, not listed out on this page, and honestly it's the family heirloom energy. 🧚

🌈 Detailed Description 🌈

A scale engine for linear scales. that's the whole job, she's specialized and she's thriving. 💅

The step size will fit into the pattern $t 1,2,5 — so it's gonna snap to those classic 1, 2, 5 vibes, iconic behavior honestly.

🔥 Member Function Documentation 🔥

💜 QwtDoubleInterval QwtLinearScaleEngine::align (const QwtDoubleInterval &interval, double stepSize) const — [protected]

Align an interval to a step size. The limits of an interval are aligned that both are integer multiples of the step size. both ends, matched up, no awkward leftover, periodt ✨

Parameters:

  • interval — Interval
  • stepSize — Step size

Returns:

  • Aligned interval

💜 void QwtLinearScaleEngine::autoScale (int maxNumSteps, double &x1, double &x2, double &stepSize) const — [virtual]

Align and divide an interval. she takes your messy interval and gives it structure, we love to see it 🦋

Parameters:

  • maxNumSteps — Max. number of steps
  • x1 — First limit of the interval (In/Out)
  • x2 — Second limit of the interval (In/Out)
  • stepSize — Step size (Out)

Implements QwtScaleEngine.

💜 QwtScaleDiv QwtLinearScaleEngine::divideScale (double x1, double x2, int maxMajSteps, int maxMinSteps, double stepSize = 0.0) const — [virtual]

Calculate a scale division. 💫

Parameters:

  • x1 — First interval limit
  • x2 — Second interval limit
  • maxMajSteps — Maximum for the number of major steps
  • maxMinSteps — Maximum number of minor steps
  • stepSize — Step size. If stepSize == 0, the scaleEngine calculates one.
bestie pay attention to that last one 👀 if you pass 0, she picks the step size herself. main character energy, fr fr.

Implements QwtScaleEngine.

💜 QwtScaleTransformation * QwtLinearScaleEngine::transformation () const — [virtual]

Return a transformation, for linear scales. that's it, that's the function, she said what she said 🌸
