PlotValues for String tags

I'm trying to get a clearer understanding of how ProcessBook and/or the PlotValues function process String tags. Based on another vCampus post, unique string value should be trended at the same y-axis point. How do the rest of the string values get placed? In the attached screenshot, the peaks in green look like they're on the same y-point, but their values are differnet. How is the placement determined for these and other string values?
