How can I make an arrow from one point in a tikz picture to another point?
In the following example, I would like to draw an arrow from the word data--which is approximately the coordinate (1982, 88)-- and have it point to the coordinate (1985, 82).
\documentclass[professionalfont, fleqn]{beamer}
\mode<presentation>
\usetheme{Warsaw}
\usetheme{CambridgeUS}
\usepackage{pgfplots}
\usetikzlibrary{arrows,shapes,positioning}
\graphicspath{{graphics/}}
\begin{document}
\frame
{
\frametitle{Frame Title}
\begin{tikzpicture}
\begin{axis}
[
axis x line = bottom,
axis y line = left,
width = 1.01\textwidth,
height = .63\textwidth, % Adjusted
ymax = 93,
ymin = 27,
ytick = {30,40,...,90},
xmax = 1993,
xmin = 1967,
xtick = {1970, 1980, ..., 1990},
]
\node[anchor=west] at (axis cs:1968.5,89.5){%
\textbullet\ Comment here about data
};
\end{axis}
\end{tikzpicture}
}
\end{document}
