- Per-signal, per-plot vertical scale state (sigVScale keyed by plotId:signalKey)
so the same signal in two plots has fully independent vscale config
- Active signal redrawn on top of all series with 2× line width for clear
visual identification; badge click toggles selection and opens/closes the
embedded vscale toolbar (click same badge again to deselect)
- Vscale configurator moved from floating popup to a slim toolbar strip
anchored inside the plot card, with an × close button
- Trigger dropdown shows one entry per array signal with [0…N-1] label;
opening it shows an index-picker dialog to choose the element
- Zoom resampling: when server returns no data for a zoomed range, fall
back to the local circular buffer instead of returning empty arrays
