pgf/tikz: String Symbols as Input Coordinates
- by red_lynx
Hi all,
I'm new to pgf so i was trying out some examples from the pgfplot manual. One example is especially relevant for my current task but, alas, it would not compile.
Here is the code:
\documentclass[11pt]{article}
\usepackage{tikz}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[symbolic x coords={a,b,c,d,e,f,g,h,i}]
\addplot+[smooth] coordinates {
(a,42)
(b,50)
(c,80)
(f,60)
(g,62)
(i,90)};
\end{axis}
\end{tikzpicture}
\end{document}
the compiler quits with the following error:
! Package PGF Math Error: Could not parse input 'a' as a floating point number,
sorry. The unreadable part was near 'a'..
I have no clue how to correct this behavior. Other plots (smooth, scatter, bar), which contain only numerical data compile fine.
Could anybody give me a hint?
Cheers
K.
