✨ NAME ✨

okay so hi bestie 🫶 this is the Library Functions Manual tea for qwtchangelog — What's new in Qwt 6.3. no cap, here's the rundown ☕💖

🎨 QwtPainter 🎨

big news: QwtPainter::polylineSplitting has been reenabled. 💅 but unfortunately, the Qt raster paint engine still has serious performance issues with rendering long polylines 😭. so it's back, but that caveat is still very much there, fr fr.

🎀 QwtPlotCurve 🎀

these two are lowkey having a binary search moment for monotonic curves 🔥:

  • QwtPlotCurve::adjacentPoint — for monotonic curves: using a binary search algo ⭐
  • QwtPlotCurve::interpolatedValueAt — for monotonic curves: using a binary search algo ✨

🌸 QwtSeriesData 🌸

  • wrong inheritances fixed ✅
  • firstSample, lastSample added 💅

💜 QwtPlotIntervalCurve 💜

QwtPlotIntervalCurve::TubeAsLines mode added. 🫶 it's a performance optimization for rendering huge datasets, and that's iconic for big-data energy, ngl 🔥.

✨ Bugfixes/Adjustments ✨

Bugfixes/Adjustments — often needed because of new Qt developments. that's the whole vibe, bestie: fixes and adjustments, periodt 🦋.

later bestie 💅 this lil page came from the Qwt User's Guide and it's all for qwtchangelog(3). mwah 🫶✨
