Current qualitative deepening pass for the FROG Waveform Chart widget family
FROG — Free Open Graphical Language
The Waveform Chart family now has a fuller public surface for instrumentation-style charting:
- structured
frog.waveform_chart_valuevalue posture, - sample payload kinds,
- timebase model,
- history retention model,
- multi-plot posture,
- scale and grid posture,
- cursor and cursor readout posture,
- legend / palette / scrollbar surfaces,
- annotation and threshold overlay surfaces,
- plot-image layer posture.
Waveform Chart remains the baseline time-ordered numeric chart widget. XY graphs, intensity graphs, mixed-signal graphs, histograms, advanced annotations, domain-specific plotting engines, and plugin renderers remain downstream profiles or future widget classes.
