Local data
Foxglove can load local data files for visualization.
Supported formats
| File extension | |
|---|---|
| ROS 1 | .bag |
| ROS 2 | .mcap, .db3 |
| MCAP | .mcap |
| PX4 ULog | .ulg |
tip
Since legacy ROS 2 .db3 files do not contain their message definitions, we recommend first converting those into self-contained MCAP files before loading into Foxglove.
Getting started
Open your recording(s) directly from your computer by:
- Dragging and dropping them into Foxglove
- Using
Cmd/Ctrl + o - Clicking Open local file(s) in the app
note
When opening multiple files, Foxglove will display the data as a single merged timeline. The files must be of the same format.
