yes, thanks, and I was getting close to that. One thing I found is the manual says the height is the distance above the y-line, which should be, but doesn't have to be positive. In fact, the time series are estimates of a cycle, and has negative values, which unfortunately are not included in my sub-sample. And the negative values are not handled properly (the series disappears for the negative values)
Also, maybe it is my bad eyesight, but in examples of the older, deprecated ggjoy package, there seem to be a slight offset added to the depth effect, which doesn't appear to be the case now, or am I missing something. There is this in the manual:
> position

I assume this refers to the ggplot2 position adjustments. Would one of those calls have that effect?
Thanks,
