Here is the syntax for the key with my gnuplot, I don't see opaque option
there. Is it because my version number is not high enough? My gnuplot
version is Version 4.4 patchlevel 3

 Syntax:
       set key {on|off} {default}
               {{inside | outside} | {lmargin | rmargin | tmargin | bmargin}
                 | {at <position>}}
               {left | right | center} {top | bottom | center}
               {vertical | horizontal} {Left | Right}
               {{no}reverse} {{no}invert}
               {samplen <sample_length>} {spacing <vertical_spacing>}
               {width <width_increment>}
               {height <height_increment>}
               {{no}autotitle {columnheader}}
               {title "<text>"} {{no}enhanced}
               {font "<face>,<size>"} {textcolor <colorspec>}
               {{no}box { {linestyle | ls <line_style>}
                          | {linetype | lt <line_type>}
                            {linewidth | lw <line_width>}}}
               {maxcols {<max no. of columns> | auto}}
               {maxrows {<max no. of rows> | auto}}
       unset key
       show key
