color
I'm about to submit an article for publication, and I need to color some label text that I'm overlaying on my figures with the overpic package/environment (some labels need to be white to be readable on some figures). Problem is, I just noticed the submission guidelines say no color packages, so the
\usepackage[pdftex]{color}
I had been using is right out. Is there a way to get a specific string (really just single characters) colored white without a color package?
Here is a way to evaluate a conditional in a small TeX script:
\documentclass{standalone}
\usepackage{tikz}
\usepackage{pgfplots}
\usepackage{pgfplotstable}
\usetikzlibrary{calc}
\begin{document}
\makeatletter
\begin{tikzpicture}
\begin{axis}[
ybar,
% Bottom nodes
% #1: the THRESHOLD after which we switch to a special display.
nodes near coords bottom/.style={
% a new feature since 1.9: allows to place markers absolutely:
scatter/position=absolute,
close to zero/.style={
at={(axis cs:\pgfkeysvalueof{/data point/x},\pgfkeysvalueof{/data point/y})},
},
big value/.style={
at={(axis cs:\pgfkeysvalueof{/data point/x},0)},
color=white, text opacity=1,
inner ysep=0.5pt,
},
every node near coord/.style={
check for zero/.code={%
\pgfmathfloatifflags{\pgfplotspointmeta}{0}{%
% If meta=0, make the node a coordinate (which doesn't have text)
\pgfkeys{/tikz/coordinate}%
}{%
\begingroup
% this group is merely to switch to FPU locally. Might be
% unnecessary, but who knows.
\pgfkeys{/pgf/fpu}%
\pgfmathparse{\pgfplotspointmeta<#1}%
\global\let\result=\pgfmathresult
\endgroup
%
% simplifies debugging:
%\show\result
%
\pgfmathfloatcreate{1}{1.0}{0}%
\let\ONE=\pgfmathresult
\ifx\result\ONE
% AH : our condition 'y < #1' is met.
\pgfkeysalso{/pgfplots/close to zero}%
\else
% ok, proceed as usual.
\pgfkeysalso{/pgfplots/big value}%
\fi
}
},
check for zero,
font=\footnotesize,
rotate=90, anchor=west,
},%
},%
ymin=0,
nodes near coords={\pgfmathprintnumber[fixed zerofill,precision=1]{\pgfplotspointmeta}},
nodes near coords bottom=10,
]
\pgfplotstableread{
% set real imag mag
1 8.7
2 5.1
3 91.8367
}\mydata
\addplot table[x index=0,y index=1,header=false] {\mydata};
\end{axis}
\end{tikzpicture}
\makeatother
\end{document}
Here is an explanation:
pgfplots 1.9: scatter/position=absolute. It allows to places markers using at=<coordinate expression> which is precisely what you want here./data point/x will always evaluate to the current points x coordinate in the context of nodes near coords (similarly for y).nodes near coords bottom into its definition.close to zero and big value. My intention is that everything below a predefined absolute threshold (which is an argument to nodes near coords bottom) will be placed using close to zero, everything else with big value. check for zero routine now checks for zero, then it also checks for the threshold and applies exactly one of close to zero or big value. close to zero keeps the plot's current color and moves the node outside of the bar.10 as argument to nodes near coords bottom.Package hyperref provides star forms of the referencing commands to get the reference without the link (and link color):
\documentclass{article}
\usepackage[colorlinks]{hyperref}
\begin{document}
\section{Hello World}
\label{hello}
Name reference with link: \nameref{hello}\\
Name reference without link: \nameref*{hello}\\
Reference with link and without color:
{\hypersetup{hidelinks}\nameref{hello}}
\end{document}

I guess this should receive downvotes instead of upvotes, but anyway:
