Code Patterns

Minimal FastSense Plot

fp = FastSense('Theme', 'dark');
fp.addLine(x, y, 'DisplayName', 'Sensor A');
fp.addThreshold(100, 'Direction', 'upper', 'Label', 'Alarm', 'ShowViolations', true);
fp.render();

Dashboard with Sensors

d = DashboardEngine('Process Monitor');
d.addWidget('fastsense', 'Title', 'Pressure', 'Tag', tagRegistry.get('pressure_a'));
d.addWidget('number', 'Title', 'Temperature', 'Tag', tagRegistry.get('temperature'));
d.addWidget('status', 'Title', 'Motor', 'Tag', motorTag);
d.render();

Live Dashboard with Events

d = DashboardEngine('Live Monitor');
d.addWidget('fastsense', 'Tag', sensorTag);
d.addWidget('timeline', 'EventStore', eventStore);
d.render();
d.startLive([]); % Timer-driven refresh

Event Detection Pipeline

config = EventConfig();
config.addSensor('pressure_a', 'Alarm', 95, 'Warning', 85, ...
                 'AlarmOff', 90, 'MinDuration', 5);
[events, detector] = config.runDetection();
viewer = EventViewer(events, sensor.X, sensor.Y);
