◆ update_charts()

q2nsviz.ui.charts.ChartCanvas.update_charts	(	self,
		state_manager,
		snap
	)

Render all four chart panels for the given simulation time.

Chart layout (top to bottom)

Live qubit count over time (step function).
Entangled states over time (step function).
Total measurements over time (step function).
Per-node qubit distribution at snap.t_ns (bar chart).

Cached series are rebuilt only when a new trace is loaded, detected by an identity change on state_manager.time_array. The shared state manager is never queried here: the controller performs the per-frame snapshot_at() call and passes the resulting Snapshot, which drives both the bar chart and the current-time marker.

Parameters

state_manager	Shared `SimulationStateManager` instance, read only for its event list and timeline.
snap	`Snapshot` at the current simulation time.
