How the figure's rows and traces are arranged, how to drop a signal onto a row, and how the layout editor adds and removes rows. Martino Ferrari Rows, layout and drag & drop

The figure is a stack of rows, 1 to 8 of them, each holding up to 4 traces. Rows share one time axis and one pair of side margins, so their y labels line up, their data areas start and end on the same two columns, and their windows cannot drift apart. The left margin holds the y labels; the right one is empty, and is there so the newest tick's label and the newest sample's ink have somewhere to land instead of sitting on the frame.

How to reach it

Drag a signal's badge from the badge bar onto a row to add a trace.

Press l, or pick Layout editor from the overflow menu, to add and remove rows: a × appears at the top left of each row and a + on each boundary between rows, including above the first and below the last.

The editor's own button in the top-right corner leaves it.
Worth knowing

A plot's own right-click menu (the same compact rows as the app's menu) holds the y-axis scale, the two fits, and Remove signal, which swaps the menu to that plot's traces plus All traces on this plot — with a Back row to return. That is how a trace comes off a row without going through the layout editor.

A drop adds a trace to the row's next free slot; it does not replace one. With four traces already on a row the drop is refused.

Inserting a row moves the rows below it with their contents. Inserting above row 1 puts what row 1 plotted onto row 2 and leaves the new row empty — the rows are not renumbered under you.

A trace is remembered by the signal's name, not by its channel number, because a new CONFIG or an enable renumbers the channels and an index would silently re-point the trace.

Adding or removing a row rebuilds the figure, which is cheap, but it also re-deals every trace. A frozen trigger event survives the rebuild: the pinned window is restated rather than re-framed on the live edge.
Example

With three traces on row 1, pressing l shows 3 buttons (one ×, two +). Clicking the + above row 1 gives 2 rows and 5 buttons, with the three traces now on row 2 — the layout probe reports exactly this as rows=2 buttons=5 traces=[0:-|1:sine,ramp,noise].
