Is there any way to show the **Pleth** in the PulseDataLineRenderer?

We use the `ArterialPressure_mmHg` for our Pleth in [our Vitals Monitor](https://gitlab.kitware.com/physiology/explorer/-/wikis/home)

You can see some [visuals in this post](https://discourse.kitware.com/t/toggling-events-in-the-event-manager/1214/2)

Which kind of match up well to [[source](https://www.amperordirect.com/pc/help-pulse-oximeter/z-what-is-oximeter-plethysmograph.html)]

Oh I get it now. And what could be the Y Min and Y Max for that?

I would guess about 120-30 mmHg… maybe 140-20 if you are going extreme

You just want to bound it to your highest/lowest systolic/diastolic pressures
