In the Online Map's "Tachograph" block, the "Tachograph graph" is one of the two graphs available when having tachograph data available on your vehicle.
This graph focuses on the vehicle rather than a single driver. Useful for:
Understanding how a specific vehicle was used throughout the day.
Seeing driver handovers and shift changes.
Checking vehicle utilization patterns.
What it shows
The tachograph graph shows what happened in that specific vehicle, giving you a clear view of its activity.
Unlike the driver’s graph, it includes two timelines — one for the main driver and one for the co-driver — so you can easily see how both drivers were using the vehicle.
The tachograph graph also makes it easy to see when different drivers took over the vehicle. You can clearly identify driver changes throughout the day, helping you understand who was driving at each moment and how the work was shared.
How to view it

Colors
Activities colors
These are the colors describing the activities the driver's have done.
| Color | Meaning | Description |
 | Blue | Rest | The driver was resting (not working, not available). |
 | Yellow | Available | The driver was available but not actively working or driving. |
 | Orange | Working | The driver was doing non-driving work (loading, paperwork, vehicle checks, etc.). |
 | Red | Driving | The driver was actively driving the vehicle. |
Data source colors
Besides the colors for driver activities, there is also a color in the background of the graph that represents where the data is coming from.
| Color | Source | Description |
 | Green | DDD files | Data from tachograph files (ddd files from the vehicle's tachograph). Complete and verified data. |
 | Red | Live data - CAN and Ignition | This is live data that is read through the vehicle's internal system. This is the primary source for most vehicles. Ignition data is combines with CAN data to improve accuracy. |
 | White | No data | There is no data here, possibly because the card was not inserted, the system cannot determine or record the driver's specific activities during that time, leaving a blank gap in the recorded timeline. |
