Hello, I am trying to remove the black border outside the pie chart and remove those percentages as well. I am a beginner so any advice would be greatly appreciated.

%create pie chart
X = [1 5]
pie(X);
%add legend
labels = {'Does not resemble Pacman','Resembles Pacman'};
L = legend(labels, 'location', 'east');
set(L, 'position', get(L, 'position') + [.3 0 0 0], ...
'fontsize', 12, 'box', 'off');
%rotate axis
ax = gca;
ax.View = [120 90];

在 MATLAB Online 中打开

The patches and text are Children of axis object. You can view them using

ax.Children
ans = 
4×1 graphics array:
Text     (83%)
Patch    (Resembles Pacman)
Text     (17%)
Patch    (Does not resemble Pacman)

To achieve the result you want, add these lines to the end of your code

ax.Children(2).EdgeAlpha = 0;  % index 2 and 4 corrosponds to the ptaches in ax.Children . If the order is different in your case change it accordingly
ax.Children(4).EdgeAlpha = 0;
delete(ax.Children([1, 3])) . % delete the text object according to index from ax.Children
