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.

    I recommend asking about the problems with datatool. – Will Robertson Nov 21 '10 at 3:21

    This is really a non-answer, so I’ll just add it as a comment: I strongly recommend not creating a pie chart at all; there are far better alternatives. See the article ‘Save the Pies for Dessert’ at perceptualedge.com/articles/08-21-07.pdf for a thorough discussion. – Karl Ove Hufthammer Dec 14 '11 at 10:39
  • @KarlOveHufthammer A pie chart has two advantages: people like it and you can see with one glance whether the pieces of the pie add up to 100%. All other charts force me to start my own calculation, instead of listening to the speech. – Keks Dose May 21 '13 at 9:39

Use the package pgf-pie, which is now available on CTAN. Usage:

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

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.

    The latest version of the package doesn't seem to redefine \text. – Torbjørn T. Nov 21 '12 at 7:05

    This is a great package! The manual is really clear and easy. What a pity that this package is not on CTAN. – Keks Dose May 21 '13 at 9:42
  • it made it's way onto CTAN: ctan.org/pkg/pgf-pie?lang=de – Boern Apr 7 '18 at 16:22
  • Great to see that it has. – A T Apr 10 '18 at 11:29

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


  % 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{max(\temp,-0.5) + 0.8}
  \node at (\midangle:\innerpos) {#3};


\foreach \p/\t in {20/type A, 4/type B, 11/type C,
                   49/type D, 16/other}



which looks like

    This is a good start. I would like to be able to enter 49.5 instead of 49 percent as well as be able to set the colors. – The Dude Sep 30 '11 at 17:07

    You can modify the code to set colors: 1 add fifth parameter to command slice: \newcommand{\slice}[5] |*2* use fifth param #5 in draw command: \draw[thick,fill=#5!10] |*3* add color to pie data: \foreach \p/\t/\c in {20/type A/red, 4/type B/blue, ... |*4* pass fifth param: \slice{\thea/100*360}{\theb/100*360}{\p\%}{\t}{\c} – fret Oct 21 '16 at 19:57

There are several packages which master that.

The first one can generate charts from data files.


Here's an example taken from the datatool manual:

  • how does one define the colours? – 3kstc Aug 14 at 5:01

Run with xelatex



\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\%)}

High and simply customizable, percent and angle totals correctible.

  • If anyone was wondering, you can define custom colours for your pie slices, etc. by setting something like \definecolor{grape}{RGB}{147,67,250} before \usepackage{tikz} (or \usepackage{pstricks}, etc.) in the preamble. Then you can just use your custom colour later on with \colorlet{color0}{grape!40}. – tjt263 Apr 9 at 11:23
  • Can you mention how to change the labels? I want to be able to write little notes where the angles are displayed. – tjt263 Apr 9 at 13:42
  • The labels à stored in the value list, as you can see in both examples. – Tarass Apr 9 at 20:49

I expanded on Robert Vollmert's example. You can now simply call the \pie command with your data and it will do the rest (it even converts data to percentages). You can also provide an optional colour palette that will be cycled over for each sector and repeated if there are more sectors than colours in your palette.

You're probably better off using pgf-pie but this was fun for me and I learned a lot. Maybe it is still simple enough for others to play with and learn from too.


% Pie Chart
% Author: Oliver Burt
% Based on Robert Vollmert's pie chart: http://www.texample.net/tikz/examples/pie-chart/


%%% Usage: \pieslice[color]{total}{start angle}{end angle}{data value}{label}
  % calculate start and end points of arc

  % calculate mid angle of arc

  % draw slice
  \draw[fill=#1] (0,0) -- (\a:1) arc (\a:\b:1) -- cycle;

  % outer label
  \node[label=\midangle:{\tiny#6}] at (\midangle:1) {};

  % inner label
  \pgfmathparse{max(\temp,-0.5) + 0.8}
  \pgfmathparse{(\b-\a)/3.6} % convert slice size to percentage
  \node at (\midangle:\innerpos) {\tiny\pgfmathprintnumber[fixed,precision=1]{\percentage}\%};

%%% Usage: \pie[{colour palette array}]{{label/value array}}
  % init colour palette
  \pgfmathparse{dim(#1)} % find N of array

  % get total for dividing pie into sectors
  \foreach \val/\name in #2 {

  \foreach \val/\name in #2 {
