[Eeglablist] plotting very small-scale signals waveform

I'm having some trouble viewing very fine-scaled signals. I'm working 
with Elekta MEG recordings (imported via File-IO), where the scale of 
the signals is many orders of magnitude smaller than EEG recordings I 
use. So if I want to view the MEG waveforms (with the plot > channel 
data (scroll) function), I need to set a very very fine scaling factor. 
The interface doesn't allow me to put in anything smaller than 0.005 as 
the scaling factor. Is there a way to around this via the command line? 
I also tried using exponent syntax (5e-3), but the same lower limit 
appears to apply.

I'm not sure if this is a bug, or an intentional feature. Any 
suggestions welcome.
