With the risk of sounding foolish, but I can't seem to find the answer anywhere. How can I set the ticklabels for the colorbar? Let's say I have the following code:
\documentclass{report}
\usepackage{tikz}
\usepackage{pgfplots}
\begin{document}
\begin{figure}
\begin{tikzpicture}
\begin{axis}[%
xmin=1, xmax=2,
ymin=1, ymax=2,
colorbar,point meta min=0.3,point meta max=5.5]
\addplot [color=black]
coordinates{(1,1)(2,2)};
\end{axis}
\end{tikzpicture}
\end{figure}
\end{document}
You'll notice the labels for the colorbar are 1, 2, 3, 4 and 5. What if I would want for instance the random 0.3, 0.6, 1, ... , 5.5?
Cheers!
