Problem with subplotting the results

1 view (last 30 days)
Hello =),
I have 5 subjects' data. Below code produces bar plots for each subject (2 separate figures (A and B) for each subject: a total of 10 plots (10 figures)). My code works perfectly but when I add subplot in my code, it does not produce the correct results. I want to plot the measures of each subject (A and B) separately at the same figure (subject 1: both plots on the same figure 1, subject 2: both plots on the same figure 2....., subject 5: both plots on the same figure 5) so that there are a total of 5 distinct figures.
Since I am having problems with the subplot, I have used the same for loop for measures A and B. It would be better if I use 1 for loop for measures A and B with subplots.
Thank you so much. =)
filename= strcat('a.xlsx');
data=xlsread(filename);
for p=1:5
dataA=data(p,2:30)
dataB=data(p,31:59)
% for measure A
figure
hold on
for k=1:length(dataA)
% subplot(2,1,1); %When I enter this, it does not work.
j=bar(k,dataA(k));
if dataA(k)==1 & dataB(k)==1
set(j,'FaceColor','b');
elseif dataA(k)==1 & dataB(k)==0
set(j,'FaceColor','r');
elseif dataA(k)==2 & dataB(k)==1
set(j,'FaceColor','k');
else
set(j,'FaceColor','y');
end
end
% for measure B
figure
hold on
for k=1:length(dataB)
% subplot(2,1,1); %When I enter this, it does not work.
j=bar(k,dataB(k));
if dataA(k)==1 & dataB(k)==1
set(j,'FaceColor','b)';
elseif dataA(k)==1 & dataB(k)==0
set(j,'FaceColor','r');
elseif dataA(k)==2 & dataB(k)==1
set(j,'FaceColor','k');
else
set(j,'FaceColor','y');
end
end
end

Now my code works as I want. Thank you for all the help. =) Below is the correct code.
filename= strcat('a.xlsx');
data=xlsread(filename);
for p=1:5
dataA=data(p,2:30)
dataB=data(p,31:59)
% for measure A
figure
subplot(2,1,1);
hold on
for k=1:length(dataA)
j=bar(k,dataA(k));
if dataA(k)==1 & dataB(k)==1
set(j,'FaceColor','b');
elseif dataA(k)==1 & dataB(k)==0
set(j,'FaceColor','r');
elseif dataA(k)==2 & dataB(k)==1
set(j,'FaceColor','k');
else
set(j,'FaceColor','y');
end
end
% for measure B
subplot(2,1,2);
hold on
for k=1:length(dataB)
j=bar(k,dataB(k));
if dataA(k)==1 & dataB(k)==1
set(j,'FaceColor','b)';
elseif dataA(k)==1 & dataB(k)==0
set(j,'FaceColor','r');
elseif dataA(k)==2 & dataB(k)==1
set(j,'FaceColor','k');
else
set(j,'FaceColor','y');
end
end
end

You're putting all the plots in the same slot when you say "subplot(2,1,1)" : into the first row, first column of a 2 row, 1 column layout. If you want length(dataB) subplots on the same figure window you'll have to change the third argument of subplot to k, and have enough slots to fit them all:
numPlots = length(dataB)
plotRows = ceil(sqrt(numPlots))
for k=1:length(dataB)
subplot(plotRows, plotRows, k); % When I enter this, it works.
j=bar(k,dataB(k));
