epsepslatexgnuplot
I have created a bash script that accesses and plots data using gnuplot. For this i have had to use the $ variable bash symbol. How can I plot an eps file where i can had a hat or tilde with special characters in the xlabels and ylabels?
$\hat{x}/ \lambda_D$
my current terminal is
set terminal postscript eps enhanced color font 'Helvetica, 18'
I would use the pgfplots package for this. You can generate the data with gnuplot by using \addplot gnuplot {<expression>};, and then read the generated data using \pgfplotstableread{\jobname.pgf-plot.table}\table. After sorting this table, you just access the first element, which now contains the local maximum.
\documentclass{article}
\usepackage{pgfplots}
\usepackage{pgfplotstable}
\begin{document}
\begin{tikzpicture}
\begin{axis}[ymin=0,ymax=0.05,xmin=0,xmax=2000,grid=both]
\addplot [domain={0:2000},samples=1000]
gnuplot {(20*x)/(100000 + 50*x + x**2)};
\pgfplotstableread{\jobname.pgf-plot.table}\table
\pgfplotstablesort[sort cmp={float >},sort key={[index] 1}]\sorted{\table}
\pgfplotstablegetelem{0}{[index] 1}\of{\sorted}
\let\maxy=\pgfplotsretval
\pgfplotstablegetelem{0}{[index] 0}\of{\sorted}
\let\maxx=\pgfplotsretval
\node at (axis cs:\maxx,\maxy)
[circle, fill, red,inner sep=1.5pt,
pin={
[fill=white]40:{(\pgfmathprintnumber{\maxx}, \pgfmathprintnumber{\maxy}})
}
] {};
\draw [red] (axis cs:\maxx,0) -- (axis cs:\maxx,1);
\end{axis}
\end{tikzpicture}
\end{document}
I'm not sure if I got you right. If you want to annotate your points with an additional orientation use the using vectors style.
Because this is TeX.SX, the solution incorporates the epslatex terminal :-).
#!/usr/bin/env gnuplot
reset
set terminal epslatex color standalone
set output 'gnuplot.tex'
set angles degrees
set xrange [0:3]
set yrange [0:4]
plot '-' using 1:2:(0.2*cos($4)):(0.2*sin($4)):3 with vectors linecolor palette notitle
# x y color angle
1 1 5 30
2 1 4 40
2 3 3 45
1 2 3 60
2 2 4 160
1 3 3 80

I think, you are looking for the
epslatexterminal. So begin your Gnuplot script withthen you can use latex notation like
this should output a
.epsfile with the plot and and the.texfile where the plot is embedded and the labels are set. You can use it with\input{output}in your LaTeX file.I am not sure how your bash script works, possibly you have to escape the
$, i.e.\$.
