There are a couple things that you may want to clarify regarding your query. Do you literally want "a single line" that identifies the mean of each curve (one line multiple means) or do you want "a single line" that identifies the mean for each curve (one vertical line per mean)? In the latter case, the -xline()- option should be helpful. Additionally, if you already have predefined values for each group, it may be easier to plot the means as individual points using -scatteri- or by adding text to the body of the graph.
HTH,
Billy
