We have created a panel bar graph with lines representing benchmark values.  We used a keylegend statement to define the line portions of the figures, but the lines are too faint to visually discern the colors or patterns easily. I suspect it is an issue of the legend's transparency so I tried to implement the opaque option but received an error.  Is the opaque option available in SAS 9.4?  If the opaque option is not available to me, does anyone have any suggestions for changing the line thickness in the legend?    Here is an excerpt of the code from the proc sgpanel:   keylegend "Norm" "Sample Mean" / down = 1 titleattrs=(color = black size = 10) noborder position = top opaque;        Here is the language from the error message:   ERROR 22-322: Syntax error, expecting one of the following: ;, ACROSS, AUTOITEMSIZE, AUTOOUTLINE, BORDER, DOWN, EXCLUDE, FILLASPECT, FILLHEIGHT, LINELENGTH, NOBORDER, OUTERPAD, POSITION, SCALE, SORTORDER, TITLE, TITLEATTRS, TYPE, VALUEATTRS.   ERROR 202-322: The option or parameter is not recognized and will be ignored.     ...
