Sample Output​

Subjects Analyzed: 1

Default​

Error: No valid data found for heatmap column 'speed'

Example Calls​

Show me where on track I'm fastest and slowest​

analyze(analyzers='track_heatmap', event='01H8SP4HK4', lap_selection='best', value_column='speed')

Creates speed heatmap of best lap with color from slow (blue/purple) to fast (yellow/red)

Visualize my throttle application on the track​

analyze(analyzers='track_heatmap', event='01H8SP4HK4', value_column='throttle', colormap='viridis')

Shows throttle position (0-100%) overlaid on track layout
