To make it short, I am searching for a 2D variant of this plot How to design a 3D donut pie chart with pgf-plot? Especially the label for each segment are important for my application. I don't need any stylish shading, segments should have constant colour.

I hope someone could help me to create a diagram like this, because i am quite new to LaTeX and the whole package stuff :)


Adapted from How can I produce a 'ring (or wheel) chart' like that on page 88 of the PGF manual?, created using the line

\wheelchart{26/cyan/Corporate,  28/orange/Plastique, 33.5/yellow/Chimique, 12.5/blue!50!red/Rhodia}


% Adjusts the size of the wheel:

% The main macro
    % Calculate total
    \foreach \value/\colour/\name in {#1} {


      % Calculate the thickness and the middle line of the wheel

      % Rotate so we start from the top

      % Loop through each value set. \cumnum keeps track of where we are in the wheel
      \foreach \value/\colour/\name in {#1} {
            \pgfmathsetmacro{\newcumnum}{\cumnum + \value/\totalnum*360}

            % Calculate the percent value
            % Calculate the mid angle of the colour segments to place the labels

            % This is necessary for the labels to align nicely
            } \edef\textanchor{\pgfmathresult}

            % Draw the color segments. Somehow, the \midrow units got lost, so we add 'pt' at the end. Not nice...
            \fill[\colour] (-\cumnum:\outerradius) arc (-\cumnum:-(\newcumnum):\outerradius) --
            (-\newcumnum:\innerradius) arc (-\newcumnum:-(\cumnum):\innerradius) -- cycle;

            % Draw the data labels
            \draw  [*-,thin] node [append after command={(\midangle:\midradius pt) -- (\midangle:\outerradius + 1ex) -- (\tikzlastnode)}] at (\midangle:\outerradius + 1ex) [xshift=\labelshiftdir*0.5cm,inner sep=0pt, outer sep=0pt, ,anchor=\textanchor]{\name: \pgfmathprintnumber{\percentage}\%};

            % Set the old cumulated angle to the new value

%      \draw[gray] (0,0) circle (\outerradius) circle (\innerradius);

% Usage: \wheelchart{<value1>/<colour1>/<label1>, ...}
\wheelchart{26/cyan/Corporate,  28/orange/Plastique, 33.5/yellow/Chimique, 12.5/blue!50!red/Rhodia}

  • awsome work! but i have a problem when using \usepackage{ngerman} \usepackage[ngerman]{babel}. do you know how to fix the problem (! Missing { inserted.) ? – MrMuh Nov 14 '12 at 17:38
  • @MrMuh: I don't have that problem. What versions of ngerman, babel and tikz are you using? (I'm using v2.5e, v3.8m and v2.10, respectively) – Jake Nov 14 '12 at 18:01

    This is very nice! It definitely belongs into a TikZ or pgfplots library! – Alexander Nov 14 '12 at 18:24
  • @Jake: Wow. The most impressive part for me is how the labels are placed! Still trying to figure it out -- Soooooo much still to learn... – Peter Grill Nov 14 '12 at 19:15
  • @Jake: I agree with Peter.. that's really a cool approach. This definitely should become a package! – Claudio Fiandrino Nov 14 '12 at 19:40
