Dear
I have a subplot which (is quite complicate). Precisely, it takes values from a table and results in plotting subplots where each subplot has a double plot: on the right I plot a line series representing an histogram for 5 values of variable kimpute, while on the right I plot a bar
The code is below. It works and achieves the attached plot. May anyone tell me how may I insert a boxplot on the right of the bar??
normPmean = min(AllPmeans(:));
normColor = max(AllPmeans(:));
WSIMS = [0.5 0.75 0.9 1 1.25];
props = 1:0.5:4
strDataset = 'DBele';
indDB = 1;
fig = figure('Name', ...
['Selected k by knn imputation (' strDataset ' dataset)']);
title(['Selected k by knn imputation (' strDataset ' dataset)'])
rows = find(AllkIMPUTE.DB == indDB); % take values from that dataset
% take values to be plotted
subTab = table(AllkIMPUTE( rows ,:).unbF, AllkIMPUTE( rows ,:).wsame, ...
AllkIMPUTE( rows ,:).kimpute, AllkIMPUTE( rows ,:).pmeannearestToMin);
subTab.Properties.VariableNames = {'unbF','wsame', 'kimpute','pmean'};
fig = figure('units','normalized','outerposition',[0 0 1 1]);
N=108; % number of samples
kPerUnbFWsame = NaN(N,numel(props),numel(WSIMS));
ind = 1;
indWsim = 0;
pmeans = zeros(numel(props)*numel(WSIMS),1); % parameter to rule the subplot
for ww = WSIMS
%kPerWsame = zeros(N-2, numel(props));
indUnbF = 0;
indWsim = indWsim +1;
for unbF = props
indUnbF = indUnbF+1;
rowSub = subTab.unbF == unbF & subTab.wsame == ww;
kPerUnbFWsame(:,indUnbF,indWsim) = subTab(rowSub,:).kimpute;
hold on; h = subplot(numel(WSIMS),numel(props),ind);
% compute my small histogram
hMio = zeros(numel(kimpute),1);
for kk=kimpute
hMio(kk) = numel(find(subTab(rowSub,:).kimpute==kk));
end
% find k that gives the maximum value in the histogram
[~, indk] = max(hMio);
rowSub = subTab.unbF == unbF & subTab.wsame == ww & subTab.kimpute == kimpute(indk);
% find the pmean related to maximum k
sz=round(mean(subTab(rowSub,:).pmean),4);
szBox = subTab(rowSub,:).pmean;
pmeans(ind) = sz;
% NOW ON THE LEFT PLOT THE SMALL HISTOGRAM
plot(kimpute,hMio);
if sz<0.1
szNew = round(sz*5000);
% ON THE RIGHT PLOT THE BAR
hold on; bar(max(kimpute)+1, 100*(normPmean/sz),0.3, 'FaceColor', [round(1-sz/normColor,2) 0 round(1-sz/normColor,2)])
if mod(ind,numel(props))==1 || mod(ind,numel(props))==0
text(max(kimpute),100*(normPmean/sz)+8, ['10^{-4}' num2str(sz*10^4)], 'FontSize',8); end
end
if (mod(ind, numel(props))==1)
ylabel(['w_{same} = ' num2str(ww)]); end
if ind>numel(props)*(numel(WSIMS)-1)
xlabel(['unbF = ' num2str(unbF)]); end
set(h,'XTick', kimpute);
set(h,'XTickLabel', cellstr(num2str([kimpute]')));
set(h,'XLim', [0, max(kimpute)+1.5]);
set(h,'YTick', max(hMio));
set(h,'YTickLabel', cellstr(num2str(max(hMio))));
set(h,'YLim', [0, N+2]);
ind = ind+1;
end
end
suplabel(['mean p for ' strDataset ' = ' num2str(mean(pmeans'))],'t')
saveas(fig,[dirSave filesep strDataset 'kimpute.jpg']);
end

...
bar(max(kimpute)+1, ...
% add boxplot onto right end of axis
NX=max(kimpute)+1; % how many locations on x axis plotted
bxplotdata=... % whatever it is that is wanted as the data
NY=numel(bxplotdata); % how many points are there -- assume is column vector
boxplot([nan(NY,NX+1) bxplotdata]) % add the boxplot with dummy placeholders for locations
...
There is no X axis variable for boxplot so you have to create enough dummy columns that the data are plotted where wanted on the x axis.
