need to plot multiple column array pairs in a matrix against each other

I have a matrix made up of 55 column arrays I want to represent the data by plotting 2 column arrays against each other. Every 5th and 6th column array is a pair that I want to plot on the same plot. However my y-variable is only selecting the first one and is then plotting against that single array against each x variable array. I included my for loop below.

figure;

hold on

for h= 4:6:size(percentIMPS100mw,2),

for i= 5:6:size(percentIMPS100mw,2)

end

plot(percentIMPS100mw(:,h),percentIMPS100mw(:,i));

end

legend(LegendCellD,'location','northwest','NumColumns',3)

xlabel('Real Photocurrent(A)')

ylabel('Imaginary Photocurrent(A)')

Your for loop is not written correctly. The 'end' before your plotting code means the inner loop will run incrementing i but not doing anything. Once that finishes, i is at the final value, and then it creates the plot.

You probably do not want nested for loops. The nested loops mean that every x vector is plotted against every y vector. It sounds like instead you want to just plot x against its paired y in the next column. You only need a single loop for that. Or just use indexing.

figure;
h = 4:6:size(percentIMPS100mw,2); 
i = 5:6:size(percentIMPS100mw,2);
plot(percentIMPS100mw(:,h),percentIMPS100mw(:,i));

xlabel('Real Photocurrent(A)')
ylabel('Imaginary Photocurrent(A)')
