ft_rejectvisual: different scales for magnet- and gradi-ometers?

[Kanal Eliezer]

Hello folks -

In using ft_rejectvisual, it seems that the magnetometer and gradiometer data is on a different scale. See this picture [1] for an example of this. The help for ft_rejectvisual suggests that I can scale the meg data differently than the eeg data, but doesn't list any way to scale different types of MEG data. Is there any way I can scale data based using a user function? For example, all channels ending with '1' are meg, '2' and '3' are grad, so I can use that. Also, I know I can view the data independently using the cfg.channel config option... I want to know if I can have it on a single screen. Thanks!
