# Increase thickness of graph lines larger than ultra thick

I have a beamer presentation with some pgfplots graphs and want to increase their thickness. I found this answer How to increase the thickness of the graph lines and remove the point?, but I found ultra thick not thick enough and I do not have enough rep. to comment.

My question is: is there a way to increase the thickness of graph lines to obtain lines larger than with the ultra thick option?

Using line width option would do the job.

\documentclass[tikz]{standalone}
\RequirePackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}
\addplot+[ultra thick, , mark=none] coordinates {(0,1.5) (1,1.5)};
\addplot+[line width=10pt, mark=none] coordinates {(0,0.5) (1,0.5)};
\end{axis}
\end{tikzpicture}
