Thanks for your reply Thanks also for asking what I really want. I start from this I am not interested to have markers of individual data. As you indicated, the interval between data is such that I get a "fat line" I would like to have a way to identify groups by a solid line with a marker For instance, Group 1 has a solid red line with traingel, group 2 a solid redline with filled circle, group 3 a solid blue line with diamonds, etc I see Figure 23.38 at page 708 of the "SAS/STAT 15.2® User’s Guide Statistical Graphics Using ODS" indicating that my desired style is part of the Default language However, I am not able to get those lines Thanks Angelo
