[FieldTrip] Missing Channel labels in Data browser

[Philipp Spachtholz]

Dear Katrin,

I had the same problem. This is what worked for me:

Apparently, at least in my case, the channel labels not showing up in 
the databrowser resulted
from are wrong specification of the fontsize in ft_databrowser.

You have to locate the line that corresponds to your viewmode 
('component' in my case, around line 1715)
and replace the

'FontSize', 18 to a relative value, e.g 0.02, so that the call to 
plotting the text looks like this:

ft_plot_text(labelx(laysel), labely(laysel), opt.hdr.label(chanindx(i)), 
'tag', 'chanlabel', 'HorizontalAlignment', 
'right','interpreter','none','FontUnits','normalized','FontSize',0.02,'FontName', 
'Arial');

I am very unsure about wether this works for other MATLAB versions but 
you can give it a try.
Just make sure to make a backup of the ft_databrowser before you make 
any changes there.

Best

Philipp
