Control Legend size when autoLegend is used with LinTicks

Posted 10 years ago

Hi,

It looks simple, but I'm been trying to solve this issue for days, but no luck yet. So, here I'm. I used "LinTicks", as customized option and another graphic option.

Here is my code. I'm always trying to make it simple, but this thing gets heavier with a graphic option (autoLegend). If you know better way, please, let me know. So, here is the code.

ClearAll["Global`*"]
Options[legendMaker] = 
  Join[FilterRules[Options[Framed], 
    Except[{ImageSize, FrameStyle, Background, RoundingRadius, 
      ImageMargins}]], {FrameStyle -> None, 
    Background -> Directive[Opacity[.7], LightGray], 
    RoundingRadius -> 10, ImageMargins -> 0, PlotStyle -> Automatic, 
    PlotMarkers -> None, "LegendLineWidth" -> 35, 
    "LegendLineAspectRatio" -> .3, "LegendMarkerSize" -> 8, 
    "LegendGridOptions" -> {Alignment -> Left, Spacings -> {.4, .1}}}];


legendMaker::usage = 
  "Create a Graphics object with legends given by the list passed as \
the first argument. The options specify any non-deafult line styles \
(using PlotStyle -> {...}) or plot markers (using PlotMarkers -> \
{...}). For more options, inspect Options[legendMaker]";

legendMaker[textLabels_, opts : OptionsPattern[]] := 
  Module[{f, lineDirectives, markerSymbols, n = Length[textLabels], 
    x}, lineDirectives = ((PlotStyle /. {opts}) /. 
       PlotStyle | Automatic :> Map[ColorData[1], Range[n]]) /. 
     None -> {None};
   markerSymbols = 
    Replace[((PlotMarkers /. {opts}) /. 
         Automatic :> (Drop[
              Normal[ListPlot[Transpose[{Range[3]}], 
                  PlotMarkers -> Automatic][[1, 2]]][[1]], -1] /. 
             Inset[x_, i__] :> x)[[All, -1]]) /. {Graphics[gr__], 
         sc_} :> Graphics[gr, 
         ImageSize -> ("LegendMarkerSize" /. {opts} /. 
             Options[legendMaker, 
              "LegendMarkerSize"] /. {"LegendMarkerSize" -> 8})], 
      PlotMarkers | None :> 
       Map[Style["", Opacity[0]] &, textLabels]] /. 
     None | {} -> Style["", Opacity[0]];
   lineDirectives = PadRight[lineDirectives, n, lineDirectives];
   markerSymbols = PadRight[markerSymbols, n, markerSymbols];
   f = Grid[
     MapThread[{Graphics[{#1 /. None -> {}, 
          If[#1 === {None} || (PlotStyle /. {opts}) === None, {}, 
           Line[{{-.1, 0}, {.1, 0}}]], 
          Inset[#2, {0, 0}, Background -> None]}, 
         AspectRatio -> ("LegendLineAspectRatio" /. {opts} /. 
             Options[legendMaker, 

              "LegendLineAspectRatio"] /. {"LegendLineAspectRatio" -> \
.2}), ImageSize -> ("LegendLineWidth" /. {opts} /. 
             Options[legendMaker, 
              "LegendLineWidth"] /. {"LegendLineWidth" -> 35}), 
         ImagePadding -> {{1, 1}, {0, 0}}], 
        Text[#3, FormatType -> TraditionalForm]} &, {lineDirectives, 
       markerSymbols, textLabels}], 
     Sequence@
      Evaluate[("LegendGridOptions" /. {opts} /. 
          Options[legendMaker,

         PointSize[_] :> PointSize[1], .01}, Infinity]], {} -> None]}]

autoLegend::usage = 
  "Simplified legending for the plot passed as first argument, with \

Options[autoLegend] = 
  Join[{Alignment -> {Right, Top}, Background -> White,

   FilterRules[Options[legendMaker], 
    Except[Alignment | Background | AspectRatio]]];
autoLegend[plot_Graphics, labels_, opts : OptionsPattern[]] :=

   align = OptionValue[Alignment]}, {lines, markers} = 
   extractStyles[plot];

autoLegend[

Here is the result.

I was able to make big text for Ticks, but I couldn't get Legend big. If you know how to make it big, please, help me. It would be very appreciable. Thank you.

Forgot to mention that I used Lintick to keep Ticks with high resolution image. When I enlarge an image without LinTicks, I lost Ticks. That's why I used LinTicks. But if you guys know to get around this, please, let me know too. Because I have to run the LinTicks package every time before I run this code to work.
