Tex use

[audunth]

LaTeX is an implicit dependency for cosmoplots. Here, we make the dependency explicit in the Readme.

Also, since Computer Modern is the default LaTeX font, we change to this - anyone with a working LaTeX installation should have access to this font, unlike 'Times' (which is not by default available on Fedora / Arch).

@engeir I've added you to check if this works on ubuntu.
@auroradh same for Mac.

I guess this depend on the latex distribution that the user has installed? Using tinytex, I run into four missing packages: (with texlive-full i guess it will just work?)

Input

Example from README

import matplotlib.pyplot as plt
import cosmoplots
plt.style.use(["cosmoplots.default"])
import numpy as np

a = np.exp(np.linspace(-3, 1, 100))

# Plotting
fig = plt.figure()
ax1 = plt.gca()
ax1.set_xlabel("X Axis")
ax1.set_ylabel("Y Axis")
base = 2  # Default is 10, but 2 works equally well
# Do plotting ...
ax1.semilogx(a)
# It is recommended to call the change_log_axis_base function after doing all the
# plotting. By default, it will try to infer the scaling used for the axis and only
# adjust accordingly.
cosmoplots.change_log_axis_base(ax1, base=base)
# Plotting
fig = plt.figure()
ax2 = plt.gca()
ax2.set_xlabel("X Axis")
ax2.set_ylabel("Y Axis")
base = 2  # Default is 10, but 2 works equally well
cosmoplots.change_log_axis_base(ax2, "x", base=base)
# Do plotting ...
# If you use "plot", the change_log_axis_base can be called at the top (along with add_axes
# etc.), but using loglog, semilogx, semilogy will re-set, and the change_log_axis_base
# function must be called again.
ax2.plot(a)
plt.savefig("test.png")  # also jpg, pdf

Yes, we should probably say it needs TeX-Live. I'll check if this is true.

Does tinytex ship with any fonts? What is the default?

[audunth]

@engeir Try with Latin Modern instead.

[engeir]

@audunth There is no difference for me whether I use the Latin Modern or serif+cm commits, same four packages need to be installed if tinytex is used.

Just tested with texlive-full, in which case it works out-of-the-box, no tlmgr install ... needed.

[audunth]

As I expect most (of our) users to have some form of texlive (I had not heard of tinytex before), I think a mention in the Readme is good enough.

On Computer Modern vs Latin Modern, it seems there are reasons to prefer Latin Modern: matplotlib/matplotlib#28172

If none of us have problems with Tex Live + Latin Modern, we stick to that.

[audunth]

We have confirmed it works out of the box on mac as well.
