Needs["PlotLegends`"] p2 = Plot[{Sin[x + Pi], Cos[x + Pi]}, {x, 0, 2 Pi}]; Plot[{Sin[x], Cos[x]}, {x, 0, 2 Pi}, PlotLegend -> {"sine", "cosine"}, LegendSize -> {.5, .25}, LegendShadow -> None, Epilog -> Transpose[{ Cases[p2, Hue[__], Infinity], Cases[p2, Line[_], Infinity]}]] Bob Hanlon ---- Robert McHugh <r62m10 at gmail.com> wrote: ============= Have made a plot which uses PlotLegend. Would like to combine this plot with another plot. Tried using Show[] to do this, but the results were not not what I expected. In the combined plot, the second plot doesn't have the same scale as the first plot. When I remove the PlotLegend option from the first plot and use show to combine the two plots all is well. Below is an example. (Though in the case I would like to run, there are about 10 different graphs in the first plot, so making the legend by hand would be time consuming.) Recommendations? Thanks.
