Label display problem with ft_topoplotER for EEG-MEG data

[Roemer van der Meij]

Hi Lucie,

Could you perhaps send the script with the relevant options you used
with a bit of data so I can try to replicate the bug? If your data has
to be larger than a 1 or 2 MB you can also send it my e-mail address
(see signature).
This would be very helpful in fixing the bug.

Thanks in advance,

Best,
Roemer
