Change the position of a pie chart

X = [0.1 0.2 0.2];
subplot(1,2,1),
pie(X);
subplot(1,2,2),
pie(X);
set(gca, 'CameraViewAngleMode', 'manual', 'CameraTargetMode', 'manual', ...
         'CameraPositionMode', 'manual');
     
ang = 3*pi/2;     
  set(gca, 'CameraUpVector', [sin(ang), cos(ang), 0]);

The solution below rotates the set of objects that create a pie chart by using an hgtransform.

The text label alignment needs updated since the initial alignment is designed to be to the left of the pie segments but after rotation, the labels should be centered above the segments. The text alignment adjustment is fairly easy for this example but if the pie chart contained all segements around the circle, a bit more work would be needed to assign the best alignment property values.

% Create initial pie chart

ax = axes();

h = pie([.167 .167 .167]);

% rotate 90 deg clockwise

ang = -90; % angle of rotation, degrees, negative is clockwise

tform = hgtransform('Parent',ax);

set(h, 'Parent', tform)

Rz = makehgtform('zrotate',ang*pi/180);

set(tform,'Matrix',Rz)

% Adjust text label alignment

tobj = findobj(h,'type','text');

set(tobj, 'VerticalAlignment', 'Bottom', 'HorizontalAlignment', 'Center')
