# Tikz - Using calculated coordinates inside the plot function [closed]

I'm wondering if its possible to use calculated coordinates inside the function plot, somehow like this:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{calc, positioning}

\begin{document}
\begin{tikzpicture}

\node (ea) at (20,10em) {$e_a$};
\draw plot coordinates{($(ea.north east) + (15,12)$) (0,0)};

\end{tikzpicture}
\end{document}


Or if I need to use something like:

\coordinate (test) at ($(ea.north east) + (15,12)$);
\draw plot coordinates{(test) (0,0)};

Did you try your example? I had no problems with it, so the apparent answer to your question is "yes". – JLDiaz Dec 10 '12 at 9:59
I have no problem compiling the example with the latest version of tikz. – m0nhawk Dec 10 '12 at 10:01
Yes I did try my example and now retrying it worked. Maybe I did some syntax mistake yesterday night and could not see due to fatigue. Thanks for the help! – Ronan Dec 10 '12 at 10:23
