....here all works, except the Legends entry for the data is a line and not a
Point...
... there is no simple way to make a common frame. Or at least I do not see such a way...
Hi, Kevin,
This is an addition to my earlier answer. Here is a way to have a common frame or panel around the two legends: one of which is PointLegend and the next is the LineLegend:
Here it is with a Panel:
lst = Transpose[{RandomReal[{0, 3}, 30],
RandomReal[{-0.03, 0.03}, 30]}] /. {x_, y_} -> {x, x*Exp[-x] + y};
ft = FindFit[lst, a + b*x*Exp[-c*x], {a, b, c}, x];
Show[{
ListPlot[lst, PlotRange -> {{0, 3.5}, Automatic}
],
Plot[a + b*x*Exp[-c*x] /. ft, {x, 0, 3},
PlotRange -> {{0, 3.5}, Automatic}, PlotStyle -> Red]
},
(* The legends are in the Epilog start here *)
Epilog -> Inset[Panel[Column[{
PointLegend[{Blue}, {" Data"}],
LineLegend[{Red}, \
{"f(x)=\!\(\*SuperscriptBox[\(x\[ExponentialE]\), \(-x\)]\)"}]
}]], Scaled[{0.8, 0.85}]]
(* End of the Legends*)
]
Here it is with the Frame:
lst = Transpose[{RandomReal[{0, 3}, 30],
RandomReal[{-0.03, 0.03}, 30]}] /. {x_, y_} -> {x, x*Exp[-x] + y};
ft = FindFit[lst, a + b*x*Exp[-c*x], {a, b, c}, x];
Show[{
ListPlot[lst, PlotRange -> {{0, 3.5}, Automatic}
],
Plot[a + b*x*Exp[-c*x] /. ft, {x, 0, 3},
PlotRange -> {{0, 3.5}, Automatic}, PlotStyle -> Red]
},
(* The legends are in the Epilog start here *)
Epilog -> Inset[Framed[Column[{
PointLegend[{Blue}, {" Data"}],
LineLegend[{Red}, \
{"f(x)=\!\(\*SuperscriptBox[\(x\[ExponentialE]\), \(-x\)]\)"}]
}], RoundingRadius -> 5], Scaled[{0.8, 0.85}]]
(* End of the Legends *)
]
Have fun.
