I'm trying to get pgfplots working with the colorbrewer library. So far, the example in the accepted answer here works for me, but as soon as I add options to the \addplot command, the colors are gone and all plots are drawn in black.
MWE: The following document produces black plots, and removing the [const plot] option fixes this, but I really do need to specify this and other options.
\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.15}
\usepgfplotslibrary{colorbrewer}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
cycle list/Dark2,
]
\addplot[const plot] {rnd};
\addplot[const plot] {rnd-1};
\addplot[const plot] {rnd-2};
\addplot[const plot] {rnd-3};
\end{axis}
\end{tikzpicture}
\end{document}
Is this a known issue with workarounds etc. or am I doing somethig wrong?

\addplot [...]by\addplot+ [...]should do the trick. – Stefan Pinnow Nov 25 '19 at 13:58
