Plot "thinks" that fn is a single function, not two. But Evaluate fixes the problem: Needs["PlotLegends`"] fn = {Sin[x], Cos[x]} Plot[Evaluate@fn, {x, 0, 2 Pi}, PlotLegend -> {"sin", "cos"}] Plot[{Sin[x], Cos[x]}, {x, 0, 2 Pi}, PlotLegend -> {"sin", "cos"}] Bobby On Wed, 20 Jun 2007 04:38:41 -0500, peter.steneteg at gmail.com <peter.steneteg at gmail.com> wrote: > I can not figure out why I get different results for these two cases. > > Needs["PlotLegends`"] > fn = {Sin[x], Cos[x]} > Plot[fn, {x, 0, 2 Pi}, PlotLegend -> {"sin", "cos"}] > Plot[{Sin[x], Cos[x]}, {x, 0, 2 Pi}, PlotLegend -> {"sin", "cos"}] > > When i use Plot[fn,... the Legend will only show one line, "sin" but > if I use the later case with Plot[{Sin[x],Cos[x]},... the Legend will > show correctly.
