Re: listplot and legend (again)

I apologise for an error in my last post.  The definition of style12
should have been either

style12 = {
           {Directive[{Red, Thick}], "Sin[x]"},
           {Directive[{Blue, Thick}], "x^Sin[x]"}
          };

in which case the rest of the example works (but the legend may not be
quite what one wants ... ) or

style12 = {
          {Graphics[{Red, Thick, Line[{{0.05, .7}, {0.25, .7}}]}],
           "Sin[x]"},
          {Graphics[{Blue, Thick,Line[{{0.05, .7}, {0.25, .7}}]}],
           "x^Sin[x]"}
          };

in which case the plot should be made with

plot12 = ListLinePlot[{data1, data2}, PlotStyle -> style12[[All, 1,
1]] ]
