Create a plot for a loop

Hey guys, thanks in advance for reading this
I have this code, that finds in surv_matrix the indixes where the matrix is different from zero. but for each one of them indices, I want to create a plot, like that, and see one plot for each indice. Is there anyway of creating a better loop, since this one only gives me the last plot. Imagining that ic=3,4,5. I want to see 3 plots, and with this code I m only seeing 1.
Thank you,
ic=find(~all(surv_matrix==0));
for idx=ic
surveillance_column=surv_matrix(:,idx)
plot(abs(freq_XQPSK),(abs(surveillance_column)),'b','linewidth',2);
continue
end

Use the 'hold on' command after your plot command, this will put all of your plots on the same axes
hold on

You should remove the color designation or at least have different designations for each iteration or else your plots will be the same color.
You also do not need the continue command, the for loop will automatically continue to the next value when it reaches the end of the iteration.
I'm not sure where you put the hold command but I get multiple lines on a single plot with the following
% Create random data with 0's in the third column
freq_XQPSK = (1:5)';
surv_matrix = rand(5,5);
surv_matrix(:,3) = 0;
% Find nonzero columns
ic=find(~all(surv_matrix==0));
% Loop
for idx=ic
surveillance_column = surv_matrix( : , idx );
figure(1) % I always designate a figure, especially when using hold commands
plot( abs(freq_XQPSK) , abs(surveillance_column) , 'LineWidth' , 2 ); hold on
end
