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*}
\end{document}
