@Karlo-Emilo I've created this PR as discussed, which can be used to demo the heatmaps/fingerprints. Happy for it to be marked as draft as they may well be no intention to merge these changes, and that would make it clearer. I have targeted the main branch, but please let me know if this is wrong. |
Looks good! We plan to test it August 27. |

The output data of the ML filters for each recording are used to plot heatmaps which are effectively fingerprints of the data passed into the ML model for training and inference. The fingerprints use filter outputs normalized to 0..1, the ML model still uses the non-normalized values and is not impacted by these changes.
If a micro:bit is connected, the live data is also displayed as a fingerprint at the right hand side of the bottom panel next to the x/y/z traces, replacing the 3D model on the data page only.
See microbit-foundation#273 for discussion regarding using this data visualization in classroom testing.
