Variably assigning names to graphs created in a loop

Hi there,

I am trying to produce 19 plots for different time series and have Matlab assign them names according to an index. With my code I achieve to name the 19 graphs according to the number i (so 1,2,..,19), but I would like to have the names of the index given to the current i (so if i is 3 in the current run the name of the graph should be HYB).

Index = 1;  % 1 = BarclaysUSCreditBondIndex, 2 = Hjrentelande, 3 = HYB, 4 = Ink1Y, 5 = Ink3Y, 6 = KFX, 7 = MSCIEmergingMarkets, 8 = MSCIEuropa, 9 = MSCIFjernstenexJapan, 10 = MSCIJapan, 11 = MSCIUSA, 12 = Real3Y, 13 = Real5Y, 14 = Real7Y, 15 = Stat2Y, 16 = Stat3Y, 17 = Stat5Y, 18 = Stat7Y, 19 = Virkobl

nIndices=3

for i=1:nIndices 
    figure
plot(Date(2:end), returns(:,i)) 
datetick('x')
xlabel('Date')
ylabel('Return')
title(sprintf(' %d' ,i))
end

I would appreciate any Tips!

Thanks in advance.

Here is how I usually do that:

IndexList = {'BarclaysUSCreditBondIndex','Hjrentelande','HYB'};
nIndices = numel(IndexList)

for i = nIndices
    figure
    plot(rand(5))
    title(['This is the plot for index ',IndexList{i}])
end

Simply use a cell array for the graph names:

graphnames = {'BarclaysUSCreditBondIndex', 'Hjrentelande', 'HYB', 'Ink1Y', 'Ink3Y', ... 
              'KFX', 'MSCIEmergingMarkets', 'MSCIEuropa', 'MSCIFjernstenexJapan', ...
              'MSCIJapan', 'MSCIUSA', 'Real3Y', 'Real5Y', 'Real7Y', 'Stat2Y', ...
              'Stat3Y', 'Stat5Y', 'Stat7Y', 'Virkobl'};

for graph = 1:nindices
    %... plot graph
    title(graphnames{graph});
end

Hi,

thanks to both of you! I didn't get @ Guillaume 's code to run, but @the cyclist 's addition works perfectly.

I really appreciate it!

Have a good day.

Hum! Apart from different variable names, both codes are identical.
