scale_if()

AxisRange & MayaFlux::Portal::Forma::Plot::AxisRange::scale_if ( std::function< bool()>  predicate )

inline

Gate auto-scaling behind an arbitrary bool-returning callable.

Any nullary callable returning bool is accepted: an atomic flag read, a node output comparison, a MappedState check, a lambda closing over external state. Implicitly enables auto_scaling.

The predicate is evaluated once per process() call before the new data-derived range is applied. Returning false keeps the current range.

// Only scale when signal exceeds a threshold:
AxisRange{}.scale_if([node]{ return node->get_last_output() > 0.5; });
 
// Gate on an atomic flag set elsewhere:
AxisRange{}.scale_if([&active]{ return active.load(); });
