I woud guess that there are similar commands for gvbars and gdots.
However, this seems not to be the case. The (dummy) example below can only
delete the gcurve and ends with an error message.

oscillation = gdisplay(xtitle='Time', ytitle='Response')
funct1 = gcurve(color=color.cyan)
funct2 = gvbars(delta=0.5, color=color.red)
funct3 = gdots(color=color.yellow)

for t in arange(-30, 74, 1):
    funct1.plot( pos=(t, 5.0+5.0*cos(-0.2*t)*exp(0.015*t)) )
    funct2.plot( pos=(t, 2.0+5.0*cos(-0.1*t)*exp(0.015*t)) )
