hi,

I have to make group boxplot into group 1 and 2. I am using function mutiple boxplot , but error is showing me undefined function of multiple_boxplot. I dont where i am going wrong, is this because of the matlab version. Please if somebody can help me in resolving this problem.

Thanks

x1=e.X1;
x2=e.X2;
X=[x1,x2];
y1=e.Y1;
y2=e.Y2;
Y=[y1,y2];
data = [X,Y]
data=cell(2,2);
for ii=1:size(data,1)
Xc{ii}=X(:,ii);
Yc{ii}=Y(:,ii);
end
data=vertcat(Xc,Yc);
xlab={'TSS','TP'};
multiple_boxplot(data',xlab,{'Malvern','Carling street'});
 color = ['c', 'y', 'c', 'y'];
h = findobj(gca,'Tag','Box');
for j=1:length(h)
   patch(get(h(j),'XData'),get(h(j),'YData'),color(j),'FaceAlpha',.5);
end
c = get(gca, 'Children');
hleg1 = legend(c(1:2);
data =
   47.2925   17.8000    2.5930    0.4560
   98.9950   41.0000    6.5235    1.8600
  247.6635    8.3940   10.2760    4.9480

multiple_boxplot is not built in to MATLAB. It looks like it is a user-contributed functoin that you can download from the File Exchange here.

multiple_boxplot.m

I see now that your code tries to mimic the syntax in the example on the FEX. That example works, but it is terrible code for a few reasons. I think I have made a better example below, but tried to keep close to the example, so it is not too confusing for you. (The code could be much cleaner if rewritten from scratch.)

% Pulling data from your online file. You can use your local file.

e = readtable("https://www.mathworks.com/matlabcentral/answers/uploaded_files/1163403/data.xlsx");

x1=e.X1;

x2=e.X2;

X=[x1,x2];

y1=e.Y1;

y2=e.Y2;

Y=[y1,y2];

z1=e.Z1;

z2=e.Z2;

Z=[z1,z2];

data=cell(2,3); % This variable is weirdly used only to get the dimension, and then overwritten later??? Would have been better to get from X directly.

for ii=1:size(data,1)

Xc{ii}=X(:,ii);

Yc{ii}=Y(:,ii);

Zc{ii}=Z(:,ii);

end

data=vertcat(Xc,Yc,Zc);

xtickLabels={'Data column 1','Data column 2'};

legendLabel = {'X','Y','Z'};

figure

multiple_boxplot(data',xtickLabels,{'X','Y','Z'});
