I want to plot a figure with $\LaTeX$ formulas as labels. A simple example looks like the following:

<<MaTeX`
Plot[Sin[x], {x, 0, 2 \[Pi]}, Frame -> True, FrameLabel -> (MaTeX /@ {"x", "\\rm{sin}(x)"})]

However, the labels sin(x) and x are too small in the figure for me and I want larger ones. How can I adjust their sizes?

In another case if the label is a figure, like

fig = Plot[Sin[x], {x, 0, 2 \[Pi]}, Frame -> True];
Export["test.pdf", fig];
lab = Import["test.pdf"] // First;
DeleteFile["test.pdf"];
Plot[Sin[x], {x, 0, 2 \[Pi]}, Frame -> True, FrameLabel -> {None, lab}]

Again, how do I adjust the label size?

  • $\begingroup$ You can set the font size for MaTeX, Plot[Sin[x], {x, 0, 2 \[Pi]}, Frame -> True, FrameLabel -> MaTeX[{"x", "\\sin x"}, FontSize -> 18]]. \sin x is better than using \rm. $\endgroup$

According to the documentation, there are two options that will affect the size of labels; you can also adjust the size of the plot to have the labels appear larger.

<< MaTeX`
SetOptions[MaTeX, "FontSize" -> 14, "Magnification" -> 1.2];
Plot[Sin[x], {x, 0, 2 \[Pi]},
 Frame -> True, FrameLabel -> (MaTeX /@ {"x", "\\rm{sin}(x)"}),
 ImageSize -> 250]

enter image description here

For your second example just use ImageSize when creating the label.

fig = Plot[Sin[x], {x, 0, 2 \[Pi]}, Frame -> True, ImageSize -> 120];
Plot[Sin[x], {x, 0, 2 \[Pi]}, Frame -> True, 
 FrameLabel -> {None, fig}]

Again, if your label is any image object you can use Show with a size option:

pic = (* some picture goes here *)
Plot[Sin[x], {x, 0, 2 \[Pi]}, Frame -> True, 
 FrameLabel -> {None, Show[pic, ImageSize -> Small]}]

enter image description here
