Livestream time series plot directly into MATLAB
I am trying to livestream the OpenBCI time series plot into MATLAB. I have both the BCILAB toolbox and lsl library. I have gotten the OpenBCI app to connect to MATLAB (numbers come up) but am stuck trying to convert this signal into a time series plot. I receive a type of plot when I type vis_stream into the command window but it is unreadable.
Any suggestions will be appreciated! I'm still learning MATLAB and OpenBCI.
Thank you!

Jacklyn, hi.
Are you applying some DSP (digital signal processing) filters to the LSL stream from the GUI? Typically a bandpass from say .5 to 45 Hz is applied. This removes the DC offset. A notch filter at the mains frequency (60 or 50 Hz), is also useful.

Thank you for the quick response! I'll try that
