Tb Off Track Output Row

Gallery / Off-track & Rails

A `direction: TB` section whose trunk stations feed off-track outputs. Each output hangs off its producer via an S -- a flow-axis lead down the trunk, a diagonal, then a flat tail into the icon -- on the side opposite the beside-trunk labels, the rotation of the LR off-track idiom, rather than leaving perpendicular or dropping onto the label side (issue #1384).

%%metro title: TB off-track output row
%% Regression for #1384: in a `direction: TB` section an off-track output
%% (producer-fed sink) hangs off its producer via an S -- a flow-axis lead down
%% the trunk, a diagonal, then a flat tail into the icon -- on the side opposite
%% the beside-trunk labels, the rotation of the LR off-track idiom.  The trunk
%% descent along the flow axis must not be read as a downward branch (which
%% would flip the output onto the label side).
