There's a nice answer to a pie chart question over here. I tried to bend it to my needs but found some aspects difficult. Specifically:

  • I'd like to be able to manually adjust the labels.

    • Rather than adding the degree labels (\newcommand{\degre}{$^\circ$}, I assume), I just want to be able to write something in manually, like a year or date or note or the variable name for instance.

    • I'd liked to have the option of replacing the percentage labels with something else too, like the actual value shown in the legend perhaps.

    • And finally, the numbers aren't formatted nicely. For instance, the value 1236 should ideally be written as 1,236.

Is this kind of customization possible? There are various similar questions about other pie chart designs, but this design is a bit different to most I've seen. Anyway the current code is below.

PS: I kept getting lost in it, so to make reading a bit quicker and easier, I've set: \begin{document} through \end{document} in bold, and:
value list={149/A,1236/R+L+D,740/N+F,346/C,75/E} in italics, so you can identify it at a glance.

  • Straight up solutions are welcome, but what would be really nice is if you could also explain a little bit about how it works, so anyone reading can maybe solve similar problems on their/my own in the future. Teach a man to fish and all that. No pressure though, just a suggestion.

The wheelchart package, which I wrote, can be used.

The colored rectangles for the data are obtained with the key data style.

The slices are shifted using the key explode.

The legend is determined by the key legend. This is a tabular which is placed in a \node. The rows are determined by the key legend row. The result of all rows can be obtained with \WClegend.

The lines are obtained with the key lines.

The numbers in the slices are obtained with the key wheel data.

enter image description here

  data style={fill=color\WCcount,draw=black},
  legend row={\tikz\fill[color\WCcount,draw=black] (0,0) rectangle (0.3,0.3); & \WCvarB: & \num{\WCvarA}},
    \node[anchor=west] at (5,3) {%
      \begin{tabular}{l@{ }lr}%
  slices style={color\WCcount,draw=black},
  start angle=0,
  total angle=180,
  wheel data=\num{\WCvarA},
  wheel data pos=0.9
  149/A/text A,
  1236/R+L+D/text B,
  740/N+F/text C,
  346/C/text D,
  75/E/text E%

First of all, please limit your scope of question to one at a time. In my opinion, your questions has sub-questions ;).

Having said that I think you can simply use pgf-pie to achieve your first two parts:

    \pie[ sum =1000 , after number =$^\circ$, radius
    =2,  text = legend]{200/A+B+C , 500/E+G+H, 300/F }

and for the 3rd part, I leave it to the tikzperts :).

enter image description here

Just make the sum=2000 and you get a semi-circle as in

    \pie[ sum =2000 , after number =$^\circ$, radius
    =2,  text = legend]{200/A+B+C , 500/E+G+H, 300/F }

enter image description here

  • Everything has subquestions, it depends how you slice it. I was trying to be thorough is all. But at it's core, it's simply about exerting control over the textual elements of a graph. If it helps, think of it as "how can we customize the various texts of this pie chart?" or something like that. That said, this actually looks pretty nice. Can it do the extra labels though, and half pies (semi-circles) too? I have no need for displaying degrees either. but keep this up, it's still nice information.

    Please check updated answer. It can do many things ;). Commented Apr 9, 2019 at 12:48

Customization pie chart with plain TikZ. The code is long, but mostly done by copy-paste. You can shorten the code with foreach. I am willing to explain more if asked.

enter image description here

% for legends
\draw[fill=#1] (-.2,-.2) rectangle (.2,.2);

(0,0)     pic[fill=red!50]{box}
          node[right=2mm]{E :}
          +(0:2.8) node[left]{75}
++(90:.6) pic[fill=yellow!50]{box} 
          node[right=2mm]{C :}
          +(0:2.8) node[left]{346}
++(90:.6) pic[fill=teal!50]{box}                  
          node[right=2mm]{N+F :}
++(90:.6) pic[fill=orange!50]{box} 
          node[right=2mm]{R+L+D :}
          +(0:2.8) node[left]{1236}
++(90:.6) pic[fill=blue!50]{box} 
          node[right=2mm]{A :}
          +(0:2.8) node[left]{149};

\def\r{5} % radius of the pie chart

% each scope is a shifted piece of the pie
(0:\r) arc(0:11:\r)--(0,0)--cycle;
\draw[gray!50] (5.5:\r) 

(11:\r) arc(11:99:\r)--(0,0)--cycle;
\draw[gray!50] (55:\r) 
node[below left,black]{$48\%$}--+(40:1) 

(99:\r) arc(99:99+52:\r)--(0,0)--cycle;
\draw[gray!50] (125:\r) 
node[below right,black]{$29\%$}--+(150:1) 

(151:\r) arc(151:151+24:\r)--(0,0)--cycle;
\draw[gray!50] (165:\r) node[right,black]{$14\%$}--+(150:1) 

(175:\r) arc(175:180:\r)--(0,0)--cycle;
\draw[gray!50] (177.5:\r) node[right,black]{$3\%$}--+(150:1)
