Create Bar Charts with different number of groups for each iteration.

Hi,

I would like to create for each iteration a bar chart. However, the number of groups changes by each iteration and I do not want to change the Var manually for each iteration. Here is my code:

for f=1:nBFonds
    figure(f)
    pInd=transpose(peersInd==f);
    Var=[TotRetB(1,f);TotRetPeers(:,pInd)]; %--> TotRetPeers(:,pInd) is a 1x26 vector. In the second iteration the values in the columns 3-5
    % will be needed. So, in total (with the value in TotRetB(1,f) the bar char will have a group of 6. For the next iteration however (depending
    % in the indicator variable pInd the columns 6-10 will create another group with TotaRet(1,3). TotRetB is a 1x5 vector. nBFonds=5
   
    bar(Var);

end

thank you for your help

Try NaN

for f=1:nBFonds
    figure(f)
    Var = nan(1,26);
    pInd=transpose(peersInd==f);
    Var1 = [TotRetB(1,f);TotRetPeers(:,pInd)]; %--> TotRetPeers(:,pInd) is a 1x26 vector. In the second iteration the values in the columns 3-5
    ii = 1:length(Var1);
    Var(ii) = Var1;
    % will be needed. So, in total (with the value in TotRetB(1,f) the bar char will have a group of 6. For the next iteration however (depending
    % in the indicator variable pInd the columns 6-10 will create another group with TotaRet(1,3). TotRetB is a 1x5 vector. nBFonds=5
    bar(Var);
