Hold on not working when plotting graph from a cell array

Hello all,

I have extracted several sheets of data from an excel file (Cellulose.xlsx) into a cell array (Cellulose) and I wanted to plot the data of each sheet on the same graph. However the graph only shows the last plot even though i have used the hold on function. Can someone suggest a solution? Thanks!

Cellulose='Cellulose.xlsx';

heating_rate={'10kmin','20kmin','30kmin','40kmin','50kmin',...
    '60kmin','70kmin','80kmin','90kmin','100kmin'};

n=length(heating_rate);
data=cell(n,1);

for idx=1:n
    data{idx}=xlsread(Cellulose, heating_rate{idx});
end

figure(1); hold on;

for i=1:n
    x1=data{n,1}(:,1)+273.15;
    y1=data{n,1}(:,3);
    plot(x1,y1);
end
hold off;

Attach the data{} cell in a .mat file so that we can try it.

This works:

figure(1)
hold on
for i=1:n
    x1=data{i,1}(:,1)+273.15;
    y1=data{i,1}(:,3);
    plot(x1,y1);
end
hold off

Thanks for your reply, but it isnt working :/

Your subscripts need to be with respect to ‘i’, not ‘n’. See my edited Answer.
