Not with the parameters you've chosen.
But if it's just animation you want, this works for me (on the mac):
animate=: 3 : 0
for_i. >:i.40 do.
'dot; pensize 4' plot wave 65 29, i, _0.5
pause 0.2
end.
)
pause=: 3 : 0
NB. pause for y seconds
if. y-: 0 do. return. end.
t1=. (|y) + t=. 6!:1''
while. t<t1 do. t=. 6!:1'' end.
i.0 0
)
animate''
Needs some tuning, though. (Plus specifying a vertical range.)
