Here is my simple code:

f0[y_] := PDF[NormalDistribution[-1, 1], y]
f1[y_] := PDF[NormalDistribution[1, 1], y]
ParametricPlot[{{f0[y], f1[y]}, {y, f1[y]}}, {y, 0, 0.5}, 
    PlotStyle -> {Blue, Red}, BaseStyle -> 18, AxesStyle -> Arrowheads[0.03], 
    PlotLegends -> Placed[LineLegend[{
        Style["density composite", FontSize -> 21],
        Style["density only", FontSize-> 21]
        }, 
        LegendFunction -> (Framed[#, RoundingRadius -> 2, FrameStyle -> LightGray] &), 
        BaseStyle -> 18], {Right, Top}]]

enter image description here

I only get the legend "density composite" but not "density only" part. I need them in the same plot. One is for the blue curve and the other for the red one.

Thank you very much

  • $\begingroup$ @Öskå version 9 I use. $\endgroup$ – Seyhmus Güngören May 18 '14 at 22:31
  • $\begingroup$ According to the documentation ParametricPlot[{{2 Cos[t], Sin[t]}, {Cos[t], 2 Sin[t]}}, {t, 0, 2 Pi}, PlotLegends -> "Expressions"] works. So it should be working with the example give in the Q&A. $\endgroup$ – Öskå May 18 '14 at 22:31
  • $\begingroup$ @Öskå But I cannot use expressions. I have this: Placed[LineLegend[{Style["Outliers", FontSize -> 21], Style["Modeling errors", FontSize -> 21]}, LegendFunction -> (Framed[#, RoundingRadius -> 2, FrameStyle -> LightGray] &), BaseStyle -> 18], {Right, Top}] $\endgroup$ – Seyhmus Güngören May 18 '14 at 22:38
  • $\begingroup$ I can not help you further since I don't have v9.. $\endgroup$ – Öskå May 18 '14 at 22:41
