I'd like a smooth 1d mesh, line the black curve, but coloured. All I'm able to get is the collection of rectangles shown in the figure below…

\documentclass{standalone}
\usepackage{pgfplots}\pgfplotsset{compat=newest}
\begin{document}\begin{tikzpicture}\begin{axis}
  \addplot [mesh,line width=20pt,domain=-1:1,samples=101] {sin(360*x)*x};
  \addplot [no marks,line width=20pt,domain=-1:1,samples=101] {sin(360*x)*x-1};
\end{axis}\end{tikzpicture}\end{document}

enter image description here

\end{axis}
\end{tikzpicture}
\end{document}

Graph with smooth colored and black curve

  • Nice hack! You basically overlaid 4 plots using offset samplings.
