You're still not giving many details of what you want.
I'd be surprised if there isn't some plotting function for digital signals in the signal processing toolbox or dsp toolbox, but as I've got neither I don't know.
In base matlab, it's fairly easy to get a plot of a digitial signal:
x = [1 1 1 0 0 1 0 1 1 0 0 0 ]; %demo data
sampleddata = timetable(x(:), 'SampleRate', 8e6, 'VariableNames', {'sample'}) %a better way to store the data
