However, even with Thickness[.02] the plot line is thick but the legend line is not. Using Thickness[.1] does give both thick, but the plot line is *too* thick. It looks as if the thickness is scaled in the legend. AbsoluteThickness in place of Thickness (setting the thickness in points) seems to do the trick: <<Graphics`Legend` Plot[{x,x^2,x^3},{x,0,2},PlotStyle->{{},Dashing[{.02}], AbsoluteThickness[3]},PlotLegend->{"f(x)","g(x)","h(x)"},LegendPosition-> {-1,-1.2},LegendSize->{1.7,.5}] ---------------------- Allan Hayes Mathematica Training and Consulting www.haystack.demon.co.uk hay at haystack.demon.co.uk Voice: +44 (0)116 271 4198 Fax: +44 (0)870 164 0565
