When setting scalings, I matched the scalings used for other channels of the same type: - eyegaze == fnirs_df_phase == radians - pupil == hbo/hbr == meters

Ok here is the built documentation for the Eyetracking tutorials. Marking as ready for review! |
| custom_scalings = dict(pupil=1e3) | ||
| raw.pick(picks="eyetrack").plot(scalings=custom_scalings) |

This ends up a bit wacky:
If you set the units and scalings it will probably be more reasonable I think

Sorry @larsoner Im not sure what you mean by setting the units and if you are referring to the eyegaze channel or pupil channel (I assume eyegaze) - Can you clarify?

I meant for plot_raw but I see now that we only have it for other viz functions like plot_evoked, so never mind! Also not sure it would actually help...

Thanks @scott-huberty ! |

looking a bit late, but why is the unit for pupil |
|
Ugh yes that seems like a bug... |

Updated
mne.defaultsso that eyegaze channels are expected to be radians and pupil size channels are expected to be meters. When specifying the scalings, I matched the scalings with other MNE channel types that have a radians/meters unit (e.g. fnirs_fd_phase for radians, hbo/hbr for meters).Updated the eyetracking tutorials such that eygaze units are converted to radians as early as possible.
Notable exceptions:
