Analize EEG recorded with MuseLab



I recorded a meditation session with MuseLab. However I do not know how to get the whole meditation EEG graphics.

I would like to get a EEG graphics with y axis in voltage and x axis with time parameters so I can analize the different frequenzy of the waves.

Could someone help me? thanks in advance
