Charts and signals

The visualizations in Lab are how you read the engine's output. This section explains every panel and how to pick what you see.

In this section

• Selecting which signals appear on the chart
• Signal categories — Biological System vs Kind, plus the Group toggle for switching between them
• The meters panel — engine-computed gauges for the seven subjective states (Energy, Focus, Calm, Mood, Social, Overwhelm, Sleep Pressure)
• The heatmap — body-system summary view
• The arousal band — autonomic state
• Playhead and simulation duration

Interaction pills on the chart

When an interaction names affected signals, a small severity-colored pill appears on those signal lines at the windows the rule is active. Click the pill to jump to the interaction detail view in the inspector.
