I wonder if there is any quick way to inspect power **averaged across all (or a subset of) channels** _than_ to inspect across [each of the individual channels](https://mne.tools/stable/_images/sphx_glr_20_sensors_time_frequency_006.png). As far as I see, `mne.time_frequency.AverageTFR` does not allow taking an average across all channels or across `picks`. No such option in the `plot` method either.

Fwiw, I am not worried about baselining.

There is, have a look at the `combine` argument 😉

```python
tfr = ...
tfr.plot(combine="mean")

```

Err - this is awkward; how could I have missed it? Many thanks.
