Package for pie charts

Question

I want to create a pie chart in LaTeX. Do you know a package which manages that? I tried datatool which uses tikz as backend but seems to be unusable due to mysterious floating point errors.

Answer 1

Use the package pgf-pie, which is not on CTAN, but on Google Code.

\begin{tikzpicture}
    \pie{10/A, 20/B, 30/C, 40/D}
\end{tikzpicture}

Note however that there are conflicts with this package and any other package that introduces the command \text—e.g.: amstext. In order to mediate these effects edit pgf-pie.sty, replacing all occurrences of: \text with: \textASDF.

Answer 2

An piechart example with pgf/tikz from texample.net by Robert Vollmert is a good starting point. I'll just quote it here for completeness:

% Pie chart
% Author: Robert Vollmert
\documentclass{article}

\usepackage{calc}
\usepackage{ifthen}
\usepackage{tikz}
\begin{document}
\newcommand{\slice}[4]{
  \pgfmathparse{0.5*#1+0.5*#2}
  \let\midangle\pgfmathresult

  % slice
  \draw[thick,fill=black!10] (0,0) -- (#1:1) arc (#1:#2:1) -- cycle;

  % outer label
  \node[label=\midangle:#4] at (\midangle:1) {};

  % inner label
  \pgfmathparse{min((#2-#1-10)/110*(-0.3),0)}
  \let\temp\pgfmathresult
  \pgfmathparse{max(\temp,-0.5) + 0.8}
  \let\innerpos\pgfmathresult
  \node at (\midangle:\innerpos) {#3};
}

\begin{tikzpicture}[scale=3]

\newcounter{a}
\newcounter{b}
\foreach \p/\t in {20/type A, 4/type B, 11/type C,
                   49/type D, 16/other}
  {
    \setcounter{a}{\value{b}}
    \addtocounter{b}{\p}
    \slice{\thea/100*360}
          {\theb/100*360}
          {\p\%}{\t}
  }

\end{tikzpicture}

\end{document}

which looks like

Answer 3

Here's an example taken from the datatool manual:

\documentclass{article}

\usepackage{datapie}

\begin{filecontents}{test.csv}
Name,Quantity
"Apples",30
"Pears",25
"Lemons,Limes",40.5
"Peaches",34.5
"Cherries",20
\end{filecontents}

\DTLloaddb{fruit}{test.csv}

\begin{document}

\begin{figure}[htbp]
\centering
\DTLpiechart{variable=\quantity,outerlabel=\name}{fruit}{%
\name=Name,\quantity=Quantity}
\caption{A pie chart}
\end{figure}

\end{document}

Answer 4

Run with xelatex

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{bera}
\usepackage{pstricks-add}

\begin{document}

\begin{pspicture}(-3,-3)(3,3)
\psChart[userColor={red!30,green!30,blue!40,gray,cyan!50,
    magenta!60,cyan},chartSep=30pt,shadow,shadowsize=5pt]{34.5,17.2,20.7,15.5,5.2,6.9}{6}{2}
\psset{nodesepA=5pt,nodesepB=-10pt}
\ncline{psChartO1}{psChart1}\nput{0}{psChartO1}{1000 (34.5\%)}
\ncline{psChartO2}{psChart2}\nput{150}{psChartO2}{500 (17.2\%)}
\ncline{psChartO3}{psChart3}\nput{-90}{psChartO3}{600 (20.7\%)}
\ncline{psChartO4}{psChart4}\nput{0}{psChartO4}{450 (15.5\%)}
\ncline{psChartO5}{psChart5}\nput{0}{psChartO5}{150 (5.2\%)}
\ncline{psChartO6}{psChart6}\nput{0}{psChartO6}{200 (6.9\%)}
\bfseries%
\rput(psChartI1){Taxes}\rput(psChartI2){Rent}\rput(psChartI3){Bills}
\rput(psChartI4){Car}\rput(psChartI5){Gas}\rput(psChartI6){Food}
\end{pspicture}

\end{document}

Answer 5

There are several packages which master that.

• datatool
• pgf/tikZ
• pstricks

The first one can generate charts from data files.
