Time-Series Plot, raw data uncentered ?

Hi, can anyone explain to me how the time-series widget plot is obtained from the raw data, and point me to the relevant codes for it? Because from what I can tell, the raw data in the .txt file created for each session is not "centered" around 0 as the baseline, but the time-series widget plots it as so. Am I missing some part in the widget/data processing code that does this?

Jeremy, hi.
The CSV raw data is unfiltered. Whereas the GUI is applying bandpass, notch, filters etc.
