[Pgfplots-features] Problem with Non-Linear Colormap

[Joan H. <joa...@ou...>]

Hey guys.
I'm interested in pgfplots in order to generate a non-linear colormap. Is there a way to get the following example to work without doing lots of "hacks"?

Kind regards,
Joan

\documentclass{article}




\usepackage{pgfplots}




\begin{document}




\begin{figure*}[!t]

\centering

\begin{minipage}[c]{\textwidth}

\begin{tikzpicture}

\pgfplotsset{

    colormap={myNewColor}{[5pt]

        rgb255(0pt)=(255,0,0);

        rgb255(511pt)=(0,255,10);

        rgb255(550pt)=(0,255,0);

        rgb255(789pt)=(100,255,0);

        rgb255(1000pt)=(0,0,255)}

}

\footnotesize

\begin{axis}[

	hide axis,

	scale only axis,

	height=0pt,

	width=0pt,

       colorbar horizontal,

	point meta min=-1,

	point meta max=1,

	colorbar style={

	    height=0.5cm,

	    width=6cm,

	    xtick={-1,0,1}

	}]

	\addplot [draw=none] coordinates {(0,0)};

\end{axis}

\end{tikzpicture}

\end{minipage}

\caption{aaa}

\end{figure*}
