PlotLegend and Show

Show all headers | View raw

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.

(* this isn't what I want *)
p1 = Plot[{Sin[x], Cos[x]}, {x, 0, 2 Pi},  PlotLegend -> {"sine", "cosine"}]
p2 = Plot[{Sin[x + \[Pi]], Cos[x + \[Pi]]}, {x, 0, 2 Pi}]
Show[p1, p2]

(* remove the legend and all is well *)
p1 = Plot[{Sin[x], Cos[x]}, {x, 0, 2 Pi} ]
p2 = Plot[{Sin[x + \[Pi]], Cos[x + \[Pi]]}, {x, 0, 2 Pi}]
Show[p1, p2]
