Inconsistent handling of whitespace with LaTeX #4954
Description
Hi matplotlib developers,
I noticed some inconstancies regarding text rendering with usetex=True.
I placed the following text with plt.text() in my plot.
begin{eqnarray*}
\phi &=& 1.00 \pm 0.10 \\
a &=& 3.00 \pm 0.30 m \\
\frac{\chi^2}{ndof} &=& 1.13
\end{eqnarray*}
If the plot is saved as .png or .pdf, the whitespace around the equal signs is to big:
If saved as .svg everything looks good:
It would be great if whitespace would be consistent in all file formats.
A possibility to align text without LaTeX would also be greatly appreciated.
Thanks

There are two PRs open (#4873, #4872) that address this. Do either of them fix this?
I think we might be delegating the equation rendering in the svg backend to your viewer.

For some reason the current matplotlib master doesn't work on my machine. So I'm not able to test the PRs at the moment.
You are right, the error lies in the svg backend or in the viewer. The pdf and png renderings are equal to what LaTeX does outside of matplotlib.
If the
align*environment is used instead ofeqnarray*with\usepackage{amsmath}in the preamble, everything is consistent across all file formats.tacaswell commentedon Aug 19, 2015
Oh, sorry I misread your post. If you are using
usetex=Truewhat you are getting as a png of the latex output embedded in your plot so it is 'correct' (in that we use latex as the reference standard for our internal mathtex layout engine which is what those PRs are working on).github-actions commentedon Mar 16, 2023
