Hi Mattew,
if you want to have a fancier legend than ShowLegend offers, you have to
do it yourself. E.g. if you want lines:
g1=Plot[Sin[x],{x,0,10}];
g2=Plot[Tan[x],{x,0,10}];
g3=Show[{g1,g2}];
g4=Graphics[{ Line[{{0,0},{1.5,0},{1.5,1},{0,1},{0,0}}],
Line[{{0.2,0.8},{0.6,0.8}}],Text["First Line",{1,.8}],Dashing[{.01,.01}],
Line[{{0.2,0.6},{0.6,0.6}}],Text["SecondLine",{1,.6}],Dashing[{.02,.01}],
Line[{{0.2,0.4},{0.6,0.4}}],Text["First Line",{1,.4}],Dashing[{.02,.02}],
Line[{{0.2,0.2},{0.6,0.2}}],Text["First Line",{1,.2}]}] ;
Show[g3,Epilog->{Inset[g4,{6.25,-1},{0,0},4,Background->White]}]
hope this helps, Daniel
