Hi Marina,
Bpod has a variant of PokesPlot (also see its use in this example protocol) - but it currently updates once per trial, when the trial is complete.
The lack of updates during the trial is historical - in older Bpod firmware/software, timing information was not returned until after the trial. There is no reason why it couldn't be added to native Bpod the future; with the current firmware, BrodyLab's PokesPlot works fine if you're using BControl with Bpod hardware.
I hope this helps,
-Josh
