No, there is no way in SAS 9.2 to get the marker character into the legend. However, there are other ways to skin the cat. I have done this before: What you want is a line segment to represent the mean and median. I use the VECTOR plot to do this. You can add the vector plot into the legend. Here, the mean values for each group are computed and added to the data. The X variable is numeric with a UDF. The values are 1, 2, 3. So, you can make the vector span from -delta to +delta on each side of the value. In your case without a grouped case it should be simpler. If you want mean and median, you can create a point pair for each. You can set the line pattern of the second to dash, and see both values in the graph and legend.
