This graph is a LAYOUT LATTICE of 5 columns.
- The first column is a SCATTERPLOT showing just the axis.,
- The second column contains the BOXPLOT
- Last three columns are scatter plots with MARKERCHAR
You cannot change just one tick value of the axis, to make it bold. However, you could replace the first column with a SCATTERPLOT using MARKERCHAR to simulate the axis. You can split the column "Study2" in to two columns, 'A' having the observation "Overall" only, other being missing. The other column 'B' will have all other observations. Now, use two separeate SCATTERPLOT statements in first column, one each with these new columns 'A' & 'B'. For the scatter plot with column 'A', set the MARKERCHARACTERATTRS=(size=10, weight=bold) to just make that one value stand out.
Here is the template code for the first column. The original scatterplot statement is commented out. You have to build the new columns study2a and study2b.:
