pie3

Create a 3-D pie chart of vector X.

X = [1 3 0.5 2.5 2];
pie3(X)

Create a 3-D pie chart and offset a slice by specifying the corresponding explode element as 1.

X = [1 3 0.5 2.5 2];
explode = [0 1 0 0 0];
pie3(X,explode)

Create a 3-D pie chart and specify the text labels.

X = 1:3;
labels = ["Taxes" "Expenses" "Profit"];
pie3(X,labels)

Create a 3-D pie chart and modify the font style of one of the labels.

First, create a 3-D pie chart with the default font styling. Specify an output argument, p, so that you can use it to customize the pie chart.

X = [1 2 3];
labels = ["Taxes" "Expenses" "Profit"];
p = pie3(X,labels);

Each slice in the pie chart has four corresponding elements in p: Patch, Surface, Patch, and Text.

p'

ans = 
  12x1 graphics array:

  Patch
  Surface    (Taxes)
  Patch
  Text       (Taxes)
  Patch
  Surface    (Expenses)
  Patch
  Text       (Expenses)
  Patch
  Surface    (Profit)
  Patch
  Text       (Profit)

Get the Text object for the label Expenses. Change its color and font size by using dot notation to set the associated properties.

t = p(8);
t.Color = "red";
t.FontSize = 14;

Compare two 3-D pie charts by plotting them in the same figure using a tiled chart layout.

Create vectors of financial data for 2010 and 2011 and a set of labels.

y2010 = [50 0 100 95];
y2011 = [65 22 97 120];
labels = ["Investments" "Cash" "Operations" "Sales"];

Create a 2-by-1 tiled chart layout. Create a pie chart for 2010 in the first tile and for 2011 in the second tile. Add a shared legend for the pie charts.

t = tiledlayout(1,2,"TileSpacing","None");
ax1 = nexttile;
pie3(ax1,y2010)
title("2010")

ax2 = nexttile;
pie3(ax2,y2011)
title("2011")

l = legend(labels);
l.Layout.Tile = "south";
