Trace

Your firmware's own channels, drawn as charts: values you log with VA_LogUserTrace, GPIO states, heap gauges, counters, symbols you poll from the Symbols view, channels a Trace Domain declares, and anything you derive in Trace Tune. This is the one view that streams while recording.

Needs: a recording with trace channels, or a live capture.

Charts

Each trace gets a chart with its own control bar and Y axis. The bar holds, left to right:

CONTROL	WHAT IT DOES
Grip	Drag the chart onto another chart's left / right / top / bottom band to split the area and dock it there; drop it on the centre to overlay it on that chart (overlaid traces share the Y scale, and a click on a trace's chip makes the axis follow that trace)
Name and value	The trace name and the value at the cursor
Normalise	Scale overlaid traces to a common range
Statistics	Last, min, max, mean and RMS of the visible window, with reference lines
Step / linear	Interpolation between samples. The firmware's registration can set the default
Gradient	Area fill under the line, or the line alone
Fit Y	Fit the Y axis to the data in view
Hide	Hides the chart; it becomes a chip in the row under the charts, and comes back on click

Dividers between charts resize them. When many charts are present, the Trace header switches between fitting them in the tile and keeping readable chart heights with scrolling. Chart sizes, overlays, display choices, and hidden channels are reused when the next recording has the same trace channels.

Display types

The firmware declares a display hint when it registers a trace, and the chart follows it: graph (line), bar, gauge (dial), counter (big number), table, histogram, toggle (on / off state), register (bit field) and angle. All of them read the same samples; only the drawing differs.

Time

Ctrl+wheel (Cmd on macOS) zooms around the pointer, Shift+wheel or a horizontal wheel pans, dragging pans; the window is shared with the Timeline.
Hovering moves the shared cursor and shows the value at the cursor on each chart; a click pins it when Sticky Cursor is on; Shift+move sweeps the selected region.
Ctrl+drag (Cmd+drag on macOS) shades a range and zooms the Timeline and all charts to it on release. Double-click pins that time and highlights the nearest row in the Event Table.
Ctrl+right-click (Cmd+right-click on macOS) adds A/B/C/... measurement markers. Their handles and adjacent deltas use a separate strip above each chart, and Clear markers removes them from every synchronized view.
Below the bottom-most charts a time axis labels the window; a chip on it follows the cursor.
When the window holds more samples than there are pixel columns, a chart draws the min / max envelope per column instead of every point, so nothing is hidden by decimation.

Live

While recording, the window's right edge glides on the wall clock and the charts fill from the right, keeping the recent history on screen; zooming in still works. When the capture stops, the charts switch to the finished recording, which holds the whole session.

Tips

Polled symbols and Trace Tune outputs appear here as ordinary channels: you can overlay a filtered signal on its raw input to judge the filter.
Overlay a task's slices with a trace by tiling the Timeline next to the Trace panel; both follow the same window and cursor.
