Performance Improvements for Waveforms

The waveform widgets become noticeably laggy when a large number of points are pushed into the waveform.

Possible ways to improve performance:

  • Disable scatter plotting
  • Disable antialiasing
  • Downsample the spectrum for visualization (while retaining raw data in the BECCurve)
  • Enable OpenGL acceleration

There are also native PyQtGraph solutions available, but their performance gains need to be evaluated. See: PlotDataItem

The decision to apply a performance boost should be made automatically based on the number of points plotted in the PyQtGraph window. The user should be notified with a label indicating when the performance boost is activated.
