I am trying to create a PGFPlots surf using the colormap viridis in a similar fashion as some examples of the PGFPlots package manual. I will get the error

Package pgfkeys Error: I do not know the key '/tikz/colormap/viridis' and I am going to ignore it. Perhaps you misspelled it. \end{axis}

when using the code

\documentclass{article}
\pagestyle{empty}                       % don't show the page number

\usepackage{graphicx}
\usepackage{algorithmic}
\usepackage{rotating}


\usepackage{tikz}
\usepackage{pgfplots}
\usepgfplotslibrary{colormaps} 
\usetikzlibrary{pgfplots.colormaps} 
\usetikzlibrary[pgfplots.colormaps] 

\begin{document}

\begin{center} 
\begin{tikzpicture}
    \begin{axis}[colormap/viridis , hide axis]
        \addplot3[surf,z buffer=sort,samples=20,domain=-1:0,y domain=0:2*pi]
        ({-2*x * cos(deg(y))},
        {-2*x* sin(deg(y))},
        -x^2+100);
    \end{axis}
\end{tikzpicture}
\end{center} 
\end{document}

I also tried colormap name=viridis, but still no cigar. Any ideas

Thanks in advance.

  • Welcome to TeX.SX!! I suspect that you just need to load a pgf library. It is better to post a full minimal working example that starts with a \documentclass command, has a minimal preamble and then \begin{document}...\end{document}. In particular, here it would be helpful to know exactly what packages you are using. This makes it much easier for people to help you --- and much more likely that they will!

  • Yes, sorry. I updated the code. Commented Mar 24, 2016 at 23:59
  • Looks like this colormap is an addon to the latest version of pgfplots. Are your Latex packages up to date?

  • As Jens PLoz mentioned the package required updating. Thanks. Commented Mar 25, 2016 at 0:36

The colormap 'viridis' is an addon to the latest version of pgfplots. After updating my Latex packages it worked for me.
