matlab 如何在饼图上既有比例又有标注

x=numE(1:end)./1e4;% cost

for i=3:1:(length(numE)+2)

    label1{i-2,1} = txtE{i,1};% label

end

ax1 = subplot(1,2,1);

explode1=[zeros(1,length(x)-1),1];

p=pie(ax1,x,explode1);

title(ax1,'Main-Cost Distribution');

%%以下为比例+标注

pText = findobj(p,'Type','text');

percentValues = get(pText,'String'); 

combinedtxt = strcat(label1,percentValues); 

for i=1:1:length(x)

    pText(i).String = combinedtxt(i);

end
