I am currently trying to make a graph with tikZ, to include it in a LaTeX article. After spending hours, I managed to get something, but not as good as I would like. There is still some problems I don't manage to fix.
My LaTeX code is the following :
Code: Select all
\documentclass[a4paper]{article}
\usepackage{pgfplots}
\usepackage{units}
\pgfplotsset{compat=1.3}% <-- moves axis labels near ticklabels
% (respects tick label widths)
\begin{document}
\begin{figure}
\centering
\begin{tikzpicture}
\tikzset{
every pin/.style={font=\tiny},
}
\begin{axis}[
hide x axis,
axis y line = left,
ylabel = {\(F(J)\) \((\unit{cm^{-1}})\)},
no markers,
xmin = -0.5,
xmax = 11,
ymin = -30,
ymax = 460
]

The problems I have are :
1) Texts are not aligned.
2) Left to the "table" legend, there is a line I don't want.
May anyone help me ?
Thanks a lot !
