I have no idea which column is which curve.
Try this:
[D,T,R] = xlsread('Kitap3.xlsx');
Q1 = D(1:15,:);
time = linspace(0, size(D,1), size(D,1));
figure
yyaxis left
plot(time, D(:,1))
hold on
plot(time, D(:,2))
yyaxis right
plot(time, D(:,3))
hold off
Experiment with the column assignments to get the result you want.
