I am drawing a timeseries graph with different groups using a BY statement. These groups are percentiles and I am drawing only the top and bottom 10 percentiles. How do I tell SAS to use dash lines for the top 10 groups and solid lines for the bottom 10 groups? Currently, it is using dash line for the top 8 or 9 groups and then solid for the rest. My code is:
proc sgplot data = sample;
where percentile<=10 or percentile>=91;
series x=t y=price/group=percentile curvelabel curvelabelpos=end curvelabelloc=outside;
run;
