Configuration​

SettingValue
Slice TypeN/A
Metadata OnlyFalse

When to Use​

  • User asks to 'show me telemetry' or 'visualize my data'
  • User wants to see detailed technique through specific corner
  • User mentions wanting to see brake points or throttle application
  • User wants to compare telemetry across laps

Key Options​

OptionDescription
corner_filterFilter to specific corner name (e.g., 'big_bend')
show_brake_pointsShow brake point markers on chart (default: False)
compare_lapsList of lap numbers to overlay for comparison (e.g., [5, 8, 12])
channelsTelemetry channels to display (default: ['speed', 'throttle', 'brake'])

Example Calls​

Show me telemetry for Big Bend in that Lime Rock session​

analyze(analyzers='telemetry_overlay', event='01H8SP4HK4', corner_filter='big_bend', show_brake_points=True)

Displays telemetry filtered to Big Bend corner with brake point markers

Compare my telemetry on laps 5 and 8​

analyze(analyzers='telemetry_overlay', event='01H8SP4HK4', compare_laps=[5, 8])

Overlays telemetry from both laps for direct comparison

Show me my best lap telemetry​

analyze(analyzers='telemetry_overlay', event='01H8SP4HK4')

Displays telemetry from the best lap (default behavior)
