I want to create a multipanel figure like that

enter image description here

and so I would like to add a letter "A", "B", etc to each of the panel I've created. I usually first create each panel with the letter and then assemble them, rather than assemble them and add the letters then:

  • For 2D panels, I am able to do so with the Epilog command:

    Epilog -> Style[Text["B", {1.1, 2.3}], 28, Bold]

but the letter is always on the panel, I can't place it on the left of the panel as is the case on the example above

  • For 3D panels, I am unable at all to use the Epilog command, so I'm looking for a good alternative

I generally use a combination of Column and Row functions to create my multipanel figure then, I find it easier to put the panels exactly where I want to, rather than using Grid or GraphicsGrid.

What solution would you use to add the reference letters to the multipanel figure?

You can also use Panel and its second and third arguments to place the labels:

 Panel[Plot3D[Sin[x + y^2], {x, -3, 3}, {y, -2, 2}, ImageSize -> 200], 
       Style["A", Bold, 14], {{Left, Top}}]

enter image description here

Or, without the frame, (* thanks: @Karsten7. *)

Panel[Plot3D[Sin[x + y^2], {x, -3, 3}, {y, -2, 2}, ImageSize -> 200],
 Style["A", Bold, 14], {{Left, Top}}, Appearance -> "Frameless"]

enter image description here


charts = {Plot3D[Sin[x + y^2], {x, -3, 3}, {y, -2, 2}, ImageSize -> 200], 
          BarChart[{{1, 2, 3}, {1, 3, 2}}], 
          Histogram[RandomVariate[WeibullDistribution[2, 1], 1000], Automatic, "Probability"], 
   ContourPlot3D[x^4 + y^4 + z^4 - (x^2 + y^2 + z^2)^2 + 3 (x^2 + y^2 + z^2) == 3, 
    {x, -2, 2}, {y, -2, 2}, {z, -2, 2}, Mesh -> None, 
    ContourStyle -> Directive[Orange, Opacity[0.8], Specularity[White, 30]], 
    ImageSize -> 300]};

labels = CharacterRange["A", "Z"][[;; 4]];
panels = Partition[Panel[#, Style[#2, Bold, 14], {{Left, Top}}] & @@@ 
            Transpose[{charts, labels}], 2];

Grid[panels, Alignment -> {Left, Top}]

    $\begingroup$ To remove the frame from the Panel one can use the option Appearance -> "Frameless". $\endgroup$

You can use Labeled to add letters outside the margins of your figures.

plot = Labeled[Framed@Plot[Sin[x], {x, 0, 5}], "A", {{Left, Top}}]


histo = Labeled[Histogram[RandomVariate[NormalDistribution[], 100]], "B", {{Left, Top}}]


sphere = Labeled[Graphics3D[{Sphere[]}], Style["C", 28, Bold], {{Left, Top}}]


Regarding the arrangement, you can start with GraphicsGrid and then rearrange the figures by hand. This needs some clicking around, though.

GraphicsGrid[{{plot, histo}, {sphere}}]
