[Eeglablist] slowly scrolling plot

[Ramón Martinez]

Hi guys,
Yes, we have introduced a few changes to improve the speed of eegplot, but
those changes has not been released yet.  However,  you can get them from
the development version in our git repo in Bitbucket (
https://bitbucket.org/sccn_eeglab/eeglab).
 Check this post from the list for more details, (

Hope this helps,
 Ramon
