在直方图/条形图中绘制两个分类数组？

假设您的数据如下所示：

yesno = categorical(randi(2,1250,1),[1 2],{'no','yes'});
race = categorical(randi(5,1250,1),1:5,{'Asian','Black','BHispanic','White','WHispanic'});

您可以执行以下操作：

% convert everything to numeric:
yn = double(yesno); 
rac = double(race);
% caluculate all frequencies:
data = accumarray([rac yn],1);
% get the categories names:
races = categories(race);   
answers = categories(yesno);
% plotting:
bar(data,0.4,'stacked');
ax = gca;
ax.XTickLabel = races; % set the x-axis ticks to the race names
legend(answers) % add a legend for the colors
colormap(lines(3)) % use nicer colors (close to your example)
ylabel('YES/NO')% set the y-axis lable
% some other minor fixes:
box off
ax.YGrid = 'on';

结果：

您可以使用以下方法制作一张桌子：

T = array2table(data.','VariableNames',races,'RowNames',answers)

输出：

T = 
           Asian    Black    BHispanic    White    WHispanic
           _____    _____    _________    _____    _________
    no     126      123      102          128      144      
    yes    145      126      128          105      123
