How do I plot many time series (iterated through in a for loop) on the same graph ?

I'm trying to do a visual comparison of a data set (n=302) on the same graph. Each file is a time series that undergoes modification within a for loop and is plotted within each iteration. Using hold hasn't been effective across iterations, and I'd like to have all of the time series plotted on the same graph. Is this possible?

for one iteration it's held but then figures start popping up 1 at a time with each time series plotted individually. They are never plotted on the same graph.

Seeing your code would help.

Here is a silly example of "hold on" working just fine. What are you doing differently?

figure
hold on
for i = 1:100
    pause(1/i)
    plot(rand(1,10))
end

(The pausing is unnecessary. It is just to show the lines getting draw one after the other.)

Holding within the for loop should be fine. It sounds like you were putting the "figure" command in the for loop, which will generate a new figure each iteration.

Well, if he put just "hold" -- not "hold on" -- inside a for loop, it will toggle the hold on and off each iteration, and would miss all but the last plot or two.
