Digital Waveform Graph fill to zero

[NikolaiLe]

Hola!

I'm doing User Interface where i wanna show impulse duration. I use Digital Waveform Graph. And I want to "fill to zero" my chart line for visibility as we can do on XY Graph. But it seems it can't be "fill to zero" on Digital Waveform Graph the same way. 

Any idea how can "fill to zero" be done on Digital Waveform Graph?

Well, it's not supported (even if you set it yourself with the property node).

So, you're on your own. Either use a XY Graph (convert each 0-1 with an offset so the ports appear above each other), or use the PlotImages properties to draw an image with the filling (and update on scale change events and data changes).

Both won't be trivial.

I guess the rational is that those signals don't really have a 0 (or -inf, or +inf). The values are true or false.
