You are apparently not running the current version of Mathematica (v9). I
will use v8.
$Version
"8.0 for Mac OS X x86 (64-bit) (October 5, 2011)"
Needs["PlotLegends`"];
Note that nested tables can be written as a single table with mutiple
iterators:
funcs = Table[
A ((Log[n] - 1)/(Log[n] + 1)),
{A, 300, 1000, 100},
{n, 4, 2000, 2}];
You used an unnecessarily complicated method to reverse the order of the
functions:
{Sequence @@ (funcs[[#1]] &) /@
{8, 7, 6, 5, 4, 3, 2, 1}} ==
(funcs[[#]] & /@ {8, 7, 6, 5, 4, 3, 2, 1}) ==
Reverse[funcs]
True
Alternatively, you could just decrement the table iterator: {A, 1000, 300,
-100)
To smooth the plot, use lines rather than numerous PlotMarkers. Either add
the option Joined->True or use ListLinePlot rather than ListPlot. Either of
these will also use lines for the legends. Lines are easier to see than
just PlotMarkers and the lines will be the same thickness as the plot lines.
If you are going to use a legend shadow, I recommend that you tone it down
by using a lighter shade of gray.
ListLinePlot[Reverse[funcs],
Frame -> True,
Axes -> False,
FrameLabel -> (Style[#, 14] & /@
TraditionalForm /@ {n, f[A, n]}),
PlotStyle -> ({AbsoluteThickness[2], #} & /@
{Yellow, Red, Blue, Green,
Orange, White, Black, Brown}), PlotLegend -> Range[1000, 300, -100],
LegendLabel -> Style["Constant A", 12],
LegendLabelSpace -> 1,
LegendSpacing -> 0.01,
ImageSize -> 800,
LegendSize -> 1.0,
LegendPosition -> {1.025, -0.225},
ShadowBackground -> GrayLevel[.75],
LegendBackground -> LightPurple,
Background -> LightGray,
Epilog -> Text[Style[
f[A , n] == A ((Log[n] - 1)/(Log[n] + 1)) //
TraditionalForm,
14], {500, 100}]]
