EL function to cause replot?

[Mike Eggleston <mikee@xxxxxxxxxxxxxx>]

Is there a way or function within EL to cause a given indicator to
replot itself? Say using three minute bars and I want the indicator
to replot itself ever 30 minutes. I know part of the code, but
what goes in the middle?

if mod(barnumber, 30) == 0 then begin
	<what goes here?>
end;
