MaTeX doesn't change fonts on axes?

Question

I am running Mathematica 11.0, and am trying to create a bar chart to insert into a LaTeX document; since the document is in LaTeX, I would like the look of the chart to be in line with this, and so have been trying to use the MaTeX package to achieve this. Having set it all up however, when I run the code, the axis labels/numbers etc aren't changed into the computer modern font as I thought they would be. Here is my code:

<<MaTeX`

BarChart[{-10, -5, 10, 50}, 
 AxesLabel -> {X-Axis, Y-Axis}, 
 ChartLabels -> {"1", "2", "3", "4"}, ChartStyle -> {"Pastel"}, 
 BaseStyle -> {FontFamily -> "Latin Modern Roman", FontSize -> 16}]

and here is what it returns (ignore the exact placing of labels, I'll fix that once I've got MaTeX working): Confused about why it wasn't working, I thought I'd try to run one of the examples given on the website to check my install of MaTeX was ok. The code given was:

texStyle = {FontFamily -> "Latin Modern Roman", FontSize -> 12};
ContourPlot[x^2 + y^4 == 1, {x, -1.2, 1.2}, {y, -1.2, 1.2},
 BaseStyle -> texStyle,
 Epilog -> {
     Arrow[{{0.1, 0.3}, {0.5, 0.80}}],
     Inset[MaTeX["x^2+y^4=1", Magnification -> 2], {0.1, 0.3}, Scaled[{0.5, 1}]]
    }] 

and on the website returned this: however when run on my version of Mathematica, returned this (ignore the sizing of the maths in the middle; this is just because I sized up the image before exporting it): What confuses me is that the axis labels in my version have not changed, as they didn't for my bar chart, even though the maths in the middle still renders fine (which suggests that MaTeX is correctly installed and working).

Any help is greatly appreciated! :)

Answer 1

The first block of code you show,

BarChart[{-10, -5, 10, 50}, AxesLabel -> {"X-Axis", "Y-Axis"}, 
 ChartLabels -> {"1", "2", "3", "4"}, ChartStyle -> {"Pastel"}, 
 BaseStyle -> {FontFamily -> "Latin Modern Roman", FontSize -> 16}]

does not use MaTeX and does not need MaTeX. All you need is to install the Latin Modern Roman font, and specify it with FontFamily.

Where this gets tricky is that the name you must use with FontFamily is different for each operating system. I use "Latin Modern Roman" in the MaTeX documentation because that's the correct form on OS X (my platform of choice). However, on Windows it is called something different. "LM Roman 12" if memory serves.

Please go to Format -> Show Fonts to reveal the font list, and check the correct name of the font on your operating system.

Another note: You are linking to MaTeX's website, but the bulk of the documentation is part of the package, and can be accessed through the Documentation Center (Mathematica's Help menu). The MaTeX tutorial included in the main documentation does mention this problem:

Answer 2

I am not sure if you want to change Axes labels to Latex only or also change the ticks. According to MaTeX web site, to also change ticks to Latex, one needs to manually typeset them to Latex.

I do not know why texStyle is not making this change automatically.

But this works. It means you have to type set them manually using MaTeX command on each item you want to show as Latex

<< MaTeX`

lb1 = MaTeX["\\text{X-Axis}", Magnification -> 1.25];
lb2 = MaTeX["\\text{Y-Axis}", Magnification -> 1.25];

BarChart[{-10, -5, 10, 50}, 
 AxesLabel -> {lb1, lb2},
 ChartLabels -> {MaTeX[#, Magnification -> 1.3] & /@ {"1", "2", "3", "4"}}, 
 ChartStyle -> {"Pastel"},
 PlotRangePadding -> Scaled[.05]
]

Although for some reason, the font is not sharp.
