Yes there is, but you'll have to work a bit harder and construct your own. It's tedious, but straightforward. First, you'll need to construct the lines that will go into your legend. lin = {{Blue, Line[{{-1, 0}, {0, 0}}]}, {Green, Line[{{-1, 0}, {0, 0}}]}}; lin = Graphics[#] & /@ lin; Next, make the legend lgd = {Transpose[{lin, {"a", "b"}}], LegendTextSpace -> 10, LegendShadow -> None, LegendPosition -> {0.2, -0.3}, LegendSize -> {0.9, 0.2} }; Finally, put it all together. FilledPlot[{Sin[x], Cos[x]}, {x, -3, 3}, PlotStyle -> {Blue, Green}, FrameTicks -> {PiScale, Automatic, None, None}, DisplayFunction -> Identity]; ShowLegend[%, lgd]; Tedious, as I said, but straightforward. There is a school of thought that says you're better off not using legends since they detract from the information. For more, see any of the books by Tufte. Regards, Dave.
