Hi everybody, I am creating multiple plots within a for loop but what I would like instead is to have just one plot with multiple lines (one created by each iteration of the for loop). Those plots share the same values for the x axis but different ranges for the y, so it would be really convenient to have them alligned on the same "line", given that I don't care about the absolute values on the y axis. Any suggestions is much appreciated!

The first one that you say: varying the same amount but btw different numbers

@Adam: the way how I usually do this is by using hold on. The problem is this does not work here, because the way how I produce the plot is by using a function in the loop. This is roughly how I do it:

for i = 1:10
    hold on
    function_to_plot(A(i)) %where A is a vector
end

But this produces multiple plots, not one plot

You should always give an explicit axes handle to all plotting instructions, e.g.

hold( hAxes, 'on' );
plot( hAxes, xData, yData,... );

etc. Then if you want things on the same axes that is where they will appear.

Then standardize the y data before plotting each line in a consistent fashion -- one way would be as Answer_327905 Another alternative might be to use the z-score of

z=(x-mu)/sigma

Many other choices possible depending upon just what the data represent as to what might make most sense.
