Sometimes, it's hard to avoid "colliding" marker labels in scatter plots, by which I mean labels that overlap each other. If I don't want to remove data points to avoid the overlap, is it possible to shift individual labels (as with TikZ nodes)? The following MWE illustrates the problem:
\documentclass{article}
\usepackage{tikz}
\usepackage{pgfplots}
\usepackage[active,tightpage]{preview}
\PreviewEnvironment{tikzpicture}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
xlabel=$a$,
ylabel=$b$
]
\addplot[blue,mark=*,mark options={fill=blue},nodes near coords,only marks,
point meta=explicit symbolic] table[meta=label] {
x y label
100 152 {Long label 1}
200 180 {Long label 2}
110 150 {Long label 3}
};
\end{axis}
\end{tikzpicture}
\end{document}
Ideally, I would like to be able to adjust selected labels left/right/up/down. Thanks!
