# Drawing the chart from tikz/pgf Manual [duplicate]

In the manual [1] on page 90, there are two charts shown. The upper one is of interest for me. (The cyclic with the percentages. It's like a loading bar.)

Could someone point me, how I could draw that? If there is the code somewhere in the manual, tell me. I wasn't able to find that.

• First, that manual is old, if you're using a somewhat recent version of TikZ, don't use that as a reference. Second: tex.stackexchange.com/questions/82727/… – Torbjørn T. Oct 25 '17 at 17:54
• Added the latest reference. Thanks for that linked thread. It comes close to that, what I want to realize. In the latest ref. it's on page 94, there is some spacings (white lines). Well I see, this thread links itselve on others with that solution I'm looking for. Thanks. I didn't know the name of that chart so far. :) – Shalec Oct 25 '17 at 18:17

The answer is found on How can I produce a 'ring (or wheel) chart' like that on page 88 of the PGF manual?

and I cite the solution:

\usepackage{tikz}

% Adjusts the size of the wheel:

% The main macro
\newcommand{\wheelchart}[1]{
% Calculate total
\pgfmathsetmacro{\totalnum}{0}
\foreach \value/\colour/\name in {#1} {
\pgfmathparse{\value+\totalnum}
\global\let\totalnum=\pgfmathresult
}

\begin{tikzpicture}
% The text in the center of the wheel

% Calculate the thickness and the middle line of the wheel

% Rotate so we start from the top
\begin{scope}[line width=\wheelwidth,rotate=90]

% Loop through each value set. \cumnum keeps track of where we are in the wheel
\pgfmathsetmacro{\cumnum}{0}
\foreach \value/\colour/\name in {#1} {
\pgfmathsetmacro{\newcumnum}{\cumnum + \value/\totalnum*360}

% Calculate the percent value
\pgfmathsetmacro{\percentage}{\value/\totalnum*100}
% Calculate the mid angle of the colour segments to place the labels
\pgfmathsetmacro{\midangle}{-(\cumnum+\newcumnum)/2}

% This is necessary for the labels to align nicely
\pgfmathparse{
(-\midangle<5?"south":
(-\midangle<85?"south west":
(-\midangle<105?"west":
(-\midangle<175?"north west":
(-\midangle<185?"north":
(-\midangle<265?"north east":
(-\midangle<275?"east":
(-\midangle<355?"south east":"south")
)
)
)
)
)
)
)
} \edef\textanchor{\pgfmathresult}

% Draw the color segments. Somehow, the \midrow units got lost, so we add 'pt' at the end. Not nice...

% Draw the data labels
\node at (\midangle:\outerradius + 1ex) [inner sep=0pt, outer sep=0pt, ,anchor=\textanchor]{\name: \value\ (\pgfmathprintnumber{\percentage}\%)};

% The 'spokes'
\foreach \i in {0,...,\value} {
}

% Set the old cumulated angle to the new value
\global\let\cumnum=\newcumnum
}

\end{scope}

\wheelchart{20/green/good,  10/yellow/medium, 9/red/bad, 5/white/neutral, 8/blue/ok}
