[FieldTrip] Axes shift using ft_multiplotER

[Ta Dinh, Son]

Dear FieldTrip community,

My name is Son Ta Dinh and I am working in the Painlab group of Markus Ploner in Munich on EEG resting state in chronic pain conditions. I have recently started using FieldTrip and am currently trying to use ft_multiplotER to create an overview of the power spectra of all the electrodes in specific frequency bands. In principle, this works without a problem. However, I have noticed that the axes of the plot are shifted so that the origin is always included in the plot, even when my data does not include the low frequencies around 0. This creates weird overlaps as can be seen in the attached figure or the picture below. Is this intended or am I missing some setting to get the right plots?

My cfg consists only of the path to the layout-file, cfg.showlabels = 'yes' and cfg.showoutline = 'yes'
My data looks like this:
Data.label: {65x1 cell}
Data.dimord: 'chan_freq'
Data.freq: [1x61 double]
Data.powspctrm: [65x61 double]
Data.cfg: [1x1 struct]

Unexpectedly, when I change the hlim to e.g. [40 60] instead of the [40 100] that is shown in the figure below, the shift becomes even more pronounced.
When using ft_singleplotER though, the axes are shown correctly, without any shifts in x- nor y-direction.
As a workaround, I have tried setting cfg.axes = 'no' and cfg.box = 'yes', which fits the plots into a box and works better, though not optimally as the labels are partially covered.

I would be grateful if anybody could point out any mistakes in my usage of ft_multiplotER or offer better alternatives/workarounds.

Best regards,

Son
