I'm trying to plot a Table of functions. Since the number of elements is unspecified, I want to specify a "repeating" graphic directive.

Supposing I have two direcives, m and s, I would like to do something like:

PlotStyle -> {m, s...}

But I can only specify

PlotStyle -> {m, s}

However, since this specification is cyclical, I get (what would be like)

{m, s, m, s, m, s...}

So I'm forced to specify

PlotStyle -> {m, s, s, s, s, s, s, s, s, s, s, s}

for the exact number of elements in the Table, and breaking the graphical presentation for another number of elements.

Is there a way I can specify a directive for a number n of first elements in the Table, and another for the remaining elements?

    $\begingroup$ One way to at least make the solution you have more manageable (ie, less code) would be something like PlotStyle -> Flatten[{m, Table[s, 10]} where 10 is the number of elements. $\endgroup$

My usual approach would be to programmatically generate the set of styles:

fns = x^Range[5];

Plot[fns, {x, -1, 1}, PlotStyle -> Prepend[Table[Black, 4], Red]]

You could also use Style to override the setting coming from PlotStyle:

Plot[Evaluate[MapAt[Style[#, Red] &, fns, 1]], {x, -1, 1}, 
 PlotStyle -> Black]

  • $\begingroup$ @BobHanlon That's a good way, except that the PlotRange will be determined by the first function. Adding PlotRange -> All may help, but not if a function has a very large range compared to others. $\endgroup$

  • $\begingroup$ @MichaelE2 - or the PlotRange can be specified as an option to Show $\endgroup$

  • $\begingroup$ @BobHanlon Yeah, I meant adding PlotRange -> All to Show[] but didn't say where it was to go. $\endgroup$

    $\begingroup$ One could also use PadRight[]: Plot[x^Range[5] // Evaluate, {x, -1, 1}, PlotStyle -> PadRight[{Red}, 5, Black]] $\endgroup$ Mar 29, 2019 at 15:04

Here's a way with an UpValue:

repPlotStyle /: Plot[f_, {x_, a_, b_}, o1___,
   repPlotStyle[PlotStyle -> {s1 : Except[_List] ..., s2_List}],
   o2___] :=
  With[{n = Length[Block[{x = (a + b)/2.}, f]]},  (* could use Length[f] *)
   With[{s = Take[
        Join[{s1}, Apply[Join, Table[s2, {(n/ Length[s2]) + 1}]]],
    Plot[f, {x, a, b}, o1, PlotStyle -> s, o2]

Plot[Evaluate[ChebyshevT[Range@11, x]], {x, -1, 1},
 PlotStyle -> {Red, {Black}} // repPlotStyle]

enter image description here

Plot[Evaluate[ChebyshevT[Range@11, x]], {x, -1, 1},
 PlotStyle -> {Red, Orange, {Black, Blue, Green}} // repPlotStyle]

enter image description here

Or tweak an internal function in the same way (not guaranteed to work in versions other than 11.3):

 Charting`padList[{a_, b_List}, n_Integer] := Take[
    Prepend[Apply[Join, Table[b, {(n/ Length[b]) + 1}]], a],
 Plot[Evaluate[ChebyshevT[Range@5, x]], {x, -1, 1},
  PlotStyle -> {Red, {Black}}]
(* same output as the first graphics *)
