plotting – Put two symbols in a legend at the same time

If I have the following data:

lengthscale1SB = {{0, 3.8070469267093143`}, {0, 
    3.6334805550267246`}, {0, 3.5421004645025067`}, {0, 
    3.1777415559882036`}, {0, 3.5382988573632863`}, {0, 
    2.8210206229841543`}};

Which plotted like:

qDSClabel = {"1 K/min", "2 K/min", "5 K/min", "10 K/min", "20 K/min", 
   "30 K/min"};

ListPlot(List /@ lengthscale1SB, Frame -> True, FrameStyle -> 16, 
 Axes -> False, GridLines -> Automatic, 
 GridLinesStyle -> Lighter(Gray, .8), 
 FrameTicks -> {Automatic, Automatic}, 
 FrameLabel -> (Style(#, 20, Bold) & /@ {"y", 
     Row({"x", " (", " units)"})}), ImageSize -> Large, 
 LabelStyle -> {Black, Bold, 14}, 
 PlotStyle -> {Red, Blue, Darker(Green), Black, Cyan, Gray}, 
 PlotLegends -> Placed(Defer /@ qDSClabel, {0.1, 0.25}))

gives:

Questions

How can I put two symbols in the legend? For example, right now it is “circle” 1 K/min, “circle” 2 K/min and so on. So, specifically, how can I put something like “cirle” “triangle” 1 K/min and so on?. Can this be done easily modifying slightly: PlotLegends -> Placed(Defer /@ qDSClabel, {0.1, 0.25})?

data – Visualisation Legend Scrollable or alternative solution?

The data visualisations that I am working with could have up to 20 categories in the legend, which presents a problem. This is due to visuals been inside a card with a fixed height.

As a result I am trying to think of a solution for handling the categories…..one option is to have a scrollable legend. I was wondering if someone from community has a better solution?

Cheers,

Chris

customizatoin plotting a set of data all at once with multiple line legend

I have a dataset like as follows:
I want to plot it and have done the following way, Its working, but main problem is that I could not control the legends. I want to change the interval between two legends and break the legends into two columns for clear visualization. Can anyone please help me?

graphics – Opacity gradient in custom legend

You can use a list of colors with desired opacities as option value for "ColorScheme". For example,

colorscheme = Append[ColorData["DarkRainbow"]@#, .01 + #] & /@ Subdivide[10];

Graphics[ChartElementData["GradientRectangle", 
   "ColorScheme" -> colorscheme,  "GradientOrigin" -> Left][{{0, 15}, {0, 2}}]]

enter image description here

You can also use colorsheme with LinearGradientImage:

LinearGradientImage[{Left, Right} -> colorscheme, {360, 40}]

enter image description here

with BarLegend:

BarLegend[{Blend[colorscheme, #] &, {0, 1}}, 
   LegendMarkerSize -> {400, 40}, LegendLayout -> "Row"]

enter image description here

and as VertexColors for Line primitives:

Graphics[{AbsoluteThickness[40], 
  Line[{15 #, 0} & /@ Subdivide[Length@colorscheme - 1], 
   VertexColors -> colorscheme]}, PlotRange -> {{0, 15}, {-1, 1}}]

enter image description here

Addendum: A function to add opacity to gradient color schemes:

addOpacity = Module[{colors = DataPaclets`ColorData`GetBlendArgument[#]},
    MapIndexed[Append[#, #2[[1]]/Length[colors]] &, colors]] &;

Examples:

SeedRandom[7]
gradientschemes = RandomSample[ColorData["Gradients"], 7];

graphics = Graphics[ChartElementData["GradientRectangle", 
      "GradientOrigin" -> Bottom, "ColorScheme" -> #][{{0, 2}, {0, 15}}], 
    ImageSize -> {40, 300}] &;

Row[Labeled[Row[{graphics @ #, graphics @ addOpacity @ #}], #, Top] & /@ 
  gradientschemes, Spacer[10]]

enter image description here

Row[Labeled[Row[BarLegend[{Function[x, Blend[#, x]], {0, 1}}, 
    LegendMarkerSize -> {30, 300}] & /@ {#, addOpacity @ #}], #, 
    Top] & /@ gradientschemes, Spacer[10]]

enter image description here

Style[Row[Labeled[Row[
      LinearGradientImage[{Bottom, Top} -> #, {30, 300}] & /@ 
      {#, addOpacity@#}, Spacer[5]], #, Top] & /@ gradientschemes, 
   Spacer[10]], 
 ImageSizeMultipliers -> {1, 1}]

eps format – Save out plot and plot legend

I am attempting to save out a plot to .eps file, but cannot get the legend to come with it. Copying and pasting the image, saving as a JPEG and converting to .eps loses too much resolution for it too look good. Is there any way that I can save out a plot with its legend directly to .eps from Mathematica?

Line chart – do you add a legend to one variable data visualisation?

How to change the legend entries in micrososft word chart?

I can’t change the legends in my micrososft word (Office 365) chart. I got the doc by mail from an other person so i don’ have the original excel table. When i click on edit data it says it could’t find the source file but nothing else.I want to change the labels in the red circle. Ignore the hungarian language.
How can i change it with only the word file?

plotting – It is possible to change the legend and the style of various plot inside the ‘show’?

I have a 2-variable function (which is not zt^2) that requires a lot of processing to plot. It would be very suitable for me if I could use the Plotstyle and Plotlegends for the various 2D plot of my 3D function on the ‘Show’ command, so I could edit it without having to plot again the graph and wait a long time for it.
I’m currently using something like the code below, illustrating my problem.

plottz = Plot(
   Evaluate@Table(z t^2, {t, {.5, .6, .7, .8, 1}}), {z, 0, 5}, 
   PlotStyle -> {Dashing({.01, .02}), Dashing({.02, .02}), 
     Dashing({.04, .02}), Dashing({.06, .01}), Dashing({5, .0})}, 
   PlotLegends -> 
    Placed(LineLegend({"t = .5 h", "t = .6 h", "t = .7 h", "t = .8 h",
        "t = 1 h"}, LabelStyle -> 10), {.3, .7}));
Show(plottz, PlotRange -> All)
