Latex not rendering with PyPlot v2.3.2, Julia v0.5.2,

[arturgower]

Hi there, great package.

Any idea why this doesn't render properly:

  using LaTeXStrings
  using Plots
  pyplot()
  plot(0:1,0:1,annotations=(0.5,0.5, L"x_l"))

Though the underscore appears correctly, the font is not standard maths LaTeX. I have updated all packages.

Do you know is this a problem with PyPlot, Plots or your package?

Thanks,
Art

It's definitely nothing to do with LaTeXStrings.

The following works fine for me in PyPlot:

using PyPlot
plot(0:1,0:1)
text(0.5,0.5,L"x_l")

If that fails for you, then it is a problem with your matplotlib installation. If it succeeds for you (i.e. shows the subscript), then it is a problem with Plots.

Good diagnosis. This test does not give any error, but also does not render LaTeX font.

For some reason this test does work for Plots with the backend pgfplots() Any idea how I might fix this? I installed the latest version of matplotlib, PyPlot, LaTeXStrings and texlive. Here are some details:

julia> Pkg.installed("PyPlot")
v"2.3.2"
julia> Pkg.installed("LaTeXStrings")
v"0.2.1"

I don't know what you mean by "does not render any LaTeX font". It shows the 1 as a subscript, what more do you want?

Matplotlib does not actually use LaTeX itself as the equation rendering engine, it uses (I think?) MathJAX mathtest with whatever fonts you have specified. If you need to use LaTeX itself, then you need pgfplots or similar.

Actually, you can configure Matplotlib to use LaTeX for text rendering if you want. See: https://matplotlib.org/users/usetex.html

You can also configure Matplotlib's mathtext to use LaTeX's computer-modern font: https://matplotlib.org/users/mathtext.html
