bar graph inside loop

for i = 1:4
    enkwh=0;
    data{i} = xlsread(filename11,i);
    figure
    PP=bar(data{i},'stacked');
    xlabel('timeframe')
    ylabel('loads')
     title (sprintf('On status of loads before scheduling %d',i))
end

this is my code.

I am reading an excel file with 4 sheets in it.

When i am plotting, instead of 4 bar graphs i am getting 3 only

i=1 bar graph is not plotted.

i am getting only for i=2,3,4

can somebody tell me why it is happening

Possibly because the data{1} cell is empty or full of NaNs. It would be easier to assess if you attached a .mat file containing the data{} cell array generated by your code.

You need not to plut xlable, ylable inside the loop.....it may be pushed out of loop.
