[Eeglablist] plotting limits

[MELIS EREN]

Hello everyone,
I am very new to using eeglab, so please excuse my question.
I am not sure why I keep taking this mistake but basically, I have three
different groups in my data (the number of participants is equal), and I am
trying to apply ERPs analysis. I use permutation statistics
with Bonferroni correction.
When I do, one of the groups on the potential axis starts a very absurd
point. I keep changing the plot limits but always different. Do you have
any suggestions?
Thank you all.
