[R] ggridges help

I have tried:

ggplot(plotFrame, aes(x = time, y = cycle, height = cycle, group = depth)) + geom_ridgeline()
ggplot(plotFrame, aes(x = time, y = depth, height = cycle, group = depth)) + geom_ridgeline()
ggplot(plotFrame, aes(x = time, y = depth, group = depth)) + geom_density_ridges()

none are producing a plot that was a ridgeline for each depth showing the time series at that depth.  The plot should be like the geom_line plot,  but as a ridgeline for each depth.
