Use Cases
- Speed Analysis: View speed patterns throughout a trip
- Fuel Monitoring: Track fuel level changes to detect consumption patterns or leaks
- Temperature Trends: Monitor engine or cargo temperature over time
- Performance Comparison: Overlay multiple metrics to find correlations
- Diagnostic Analysis: Investigate specific time periods for issues
No Data Found
If "No data found" appears:
- Check that the vehicle was active during the selected dates
- Verify the vehicle's GPS device reports the selected data types
- Some data types depend on specific sensors being installed
