# Pgfplots: How do I change plot line width independently of axis line width?

I can use something like \pgfplotsset{every axis/.append style={line width=1pt}} to make all lines 1pt thick, but I would like to make only the plot lines thicker. I can do this on a per-plot-basis with \addplot [thick] ..., but how can I set it for all plots?

I found this non-obvious to find out, but there is a plot "type" or whatever the name is, which means, this will work:

\begin{tikzpicture}[every plot/.append style={very thick}]


Or

\begin{tikzpicture}[every axis plot/.append style={very thick}]


Or

\pgfplotsset{every axis plot/.append style={very thick}}


Make sure to also use "every axis plot" in the \pgfplotsset in order to work properly.
