单图中的 MATLAB 多个(平行)箱线图

我在 MATLAB 中使用箱线图函数。我需要为 6 个“XTicks”绘制 6 个不同数据集的箱线图,即 x 轴上的每个刻度线应包含 6 个相应的框、晶须、中线和其域内的异常值集。我尝试通过为每个变量设置偏移量来操纵“XTick”属性,但它不适用于 boxplot(),因为它适用于普通 plot()。我也无法添加图例。

我的问题的一个 3 变量等价物如下:

以下是需要修改的代码片段

TreadmillData = randi([20,200],69,6);
Speeds = {'1.5mph' '2.5mph' '3.5mph' '4.5mph' '5.5mph' '6.5mph'};
DeviceColors = {'r' 'g' 'c' [0.5 0 0.5] 'b' [1 0.5 0]};
Pedometer1 = TreadmillData(1:7:end,:);
Pedometer2 = TreadmillData(2:7:end,:);
Pedometer3 = TreadmillData(3:7:end,:);
Pedometer4 = TreadmillData(4:7:end,:);
Pedometer5 = TreadmillData(5:7:end,:);
Pedometer6 = TreadmillData(6:7:end,:);

GroupedData = {Pedometer1 Pedometer2 Pedometer3 Pedometer4 Pedometer5 Pedometer6};

legendEntries = {'dev1' 'dev2' 'dev3' 'dev4' 'dev5' 'dev6'};

figure;
Xt = 20:20:120;
Xt_Offset = [-15,-10,-5,5,10,15];

for i=1:6
boxplot(GroupedData{i},'Color',DeviceColors{i});
set(gca,'XTick',Xt+Xt_Offset(i));
if i==3
set(gca,'XTickLabel',Speeds);
end
hold on;
end
xlabel('Speed');ylabel('Step Count'); grid on;
legend(legendEntries);

如有任何帮助,我们将不胜感激!

最佳答案

我已经对您的代码进行了一些修改。我已经在 R2014b 中对此进行了测试。

TreadmillData = randi([20,200],69,6);
Speeds = {'1.5mph' '2.5mph' '3.5mph' '4.5mph' '5.5mph' '6.5mph'};
DeviceColors = {'r' 'g' 'c' [0.5 0 0.5] 'b' [1 0.5 0]};
Pedometer1 = TreadmillData(1:7:end,:);
Pedometer2 = TreadmillData(2:7:end,:);
Pedometer3 = TreadmillData(3:7:end,:);
Pedometer4 = TreadmillData(4:7:end,:);
Pedometer5 = TreadmillData(5:7:end,:);
Pedometer6 = TreadmillData(6:7:end,:);

GroupedData = {Pedometer1 Pedometer2 Pedometer3 Pedometer4 Pedometer5 Pedometer6};

legendEntries = {'dev1' 'dev2' 'dev3' 'dev4' 'dev5' 'dev6'};

N = numel(GroupedData);
delta = linspace(-.3,.3,N); %// define offsets to distinguish plots
width = .2; %// small width to avoid overlap
cmap = hsv(N); %// colormap
legWidth = 1.8; %// make room for legend

figure;
hold on;

for ii=1:N %// better not to shadow i (imaginary unit)
%if ii~=ceil(N/2)
% labels = repmat({''},1,N); %// empty labels
%else
labels = Speeds; %// center plot: use real labels
%end
boxplot(GroupedData{ii},'Color', DeviceColors{ii}, 'boxstyle','filled', ...
'position',(1:numel(labels))+delta(ii), 'widths',width, 'labels',labels)
%// plot filled boxes with specified positions, widths, labels
plot(NaN,1,'color',DeviceColors{ii}); %// dummy plot for legend
end
xlabel('Speed'); ylabel('Step Count'); grid on;
xlim([1+2*delta(1) numel(labels)+legWidth+2*delta(N)]) %// adjust x limits, with room for legend

legend(legendEntries);
