I created different plots with matplotlib, which I export as .pgf files. I then import these plots again in latex to display them in my document. This process works fine with the following code:
matplotlib example code:
import matplotlib.pyplot as plt
import numpy as np
t = np.arange(0.0, 2.0, 0.01)
s = 1 + np.sin(2 * np.pi * t)
fig, ax = plt.subplots(1,1)
ax.plot(t, s)
ax.set(xlabel='time (s)', ylabel='voltage (mV)', title='About as simple as it gets, folks')
ax.legend(["Test label long"])
ax.grid()
fig.savefig("test.pgf", bbox_inches='tight', format='pgf')
plt.show()
Latex:
\documentclass{article}
\usepackage{pgf}
\begin{document}
\begin{figure}[htbp]
\centering
\resizebox{0.6\textwidth}{!}{
\input{test.pgf}
}
\end{figure}
\end{document}
Resulting plot:
I want to include this plot in a presentation as well. So, I created a simple presentation with beamer and used the following code to include the plot:
\documentclass[11pt,t,usepdftitle=false,aspectratio=169]{beamer}
\RequirePackage[T1]{fontenc}
\RequirePackage[scaled=.9]{berasans}
\begin{document}
\begin{frame}
\frametitle{My Title}
\begin{figure}[htbp]
\centering
\resizebox{0.6\textwidth}{!}{
\input{test.pgf}
}
\end{figure}
\end{frame}
\end{document}
The problem now is that the legend label is not completely inside the legend anymore. You can see it (red circle) in the following image:
I tried different things to scale the plots, but nothing changes the output. The problem occurs also with the axis labels (not shown in the posted example). I suspect that it has to do with the scaling of the text in the plots but I cannot figure out how to control it. Any help would be greatly appreciated!
EDIT: As suggested by the comment I added the latex code to directly reproduce the problem. When creating the example I noticed that the problem was coming from the theme I have to use.
I could narrow down the problem to the two \RequirePackage statements that I included in the beamer code example. Interestingly, if only one package is included the plot appears normal, but if I include both the problem occurs. Could it be that these two packages are somehow conflicting?
Also, I notice that the length of the label changes if I change the scaling factor of \RequirePackage[scaled=.9]{berasans}. Could it be that this scaling factor is "wrong" in the theme I have to use?
