biphasic square wave with interpulsation intervals

[benoosuke]

So I'm trying to get my graph to look like the copy and pasted image however I already have knobs and buttons to control duty cycle, amplitude, and frequncy.  Basically I just have created the square wave, I just need a way to insert an interval and display it on a waveform graph since there is no option when simulating the signal.  Thanks!

It would be helpful to see your code. But if I were doing it I would define the waveform as a repeating series of three time intervals: a high time, a low time and an off time.
