`labkit.app.layout.plotArea`

Add one or more axes rendered by an App-owned renderer.

Syntax

node = labkit.app.layout.plotArea(id, renderer, Name=Value)

Declares axes and their one App-owned renderer. The renderer is declared here once; a view snapshot supplies only its current model.

id: Unique MATLAB identifier for the layout target.
renderer: Scalar function handle renderer(axesById,model) with no output. axesById is always a scalar struct with one graphics axes field per declared AxisIds value, including single-axis plots.

Title: Reader-facing panel title or blank. Default: blank.
Layout: Axes arrangement: "single", "pair", or "stack". Default: "single" for one axis and "stack" for multiple axes.
AxisIds: Unique MATLAB identifier row. Default: "main".
AxisTitles: One title per axis. Default: axis IDs.
XLabels: One x-axis label per axis. Default: blank.
YLabels: One y-axis label per axis. Default: blank.
ColumnWidths: One positive pixel, "fit", or "1x" value per axis for pair layout. Default: equal flexible widths.
RowHeights: One positive pixel, "fit", or "1x" value per axis for stack layout. Default: equal flexible heights.
ScrollZoomAxes: One "xy", "x", or "y" value per axis. Default: "xy".
ViewModes: App-owned mode labels. Default: strings(1,0).
OnValueChanged: Scalar callback state = callback(state,value,context). Default: [].
Interactions: Row cell array returned by named labkit.app.interaction.* declarations. Default: {}.

Throws labkit:app:contract:* for invalid IDs, options, or handlers.

node = labkit.app.layout.plotArea("preview", @drawTrace, ...
AxisIds="trace");
