Hi, I am trying to plot graphs in a for loop over one another for which, I am using the following code:
for secs=0.75:0.25:1.50
[ etf , decayFct , etfFreq , buildUpNorm , PNR ]=calcEtfSch(data,f_sampl,secs,data_point);
lgSch=10*log10(decayFct);
plT(lgSch,etfFreq);
hold on;
axis([ 0 1.5 -60 0 ]);
xticks([0 .25 0.5 0.75 1.00 1.25 1.50 ])
title( 'Schroeder curves with differing upper integration limits' )
end
However, I get 4 different plots rather than them being on the same graph. I will be glad to get some help.

Where are you plotting?

My bad. The plT function is my plotting function. Following is the code:
function [timLen]=plT(data,sampling_freq)
delta_t=1/sampling_freq;
dataLen=length(data);
timVct=(0:dataLen-1)*delta_t;
timLen=timVct(end);
figure;
plot(timVct,data,'Linewidth',2)
hold on;
end

Each figure() call creates a new figure. You should remove the figure() call.
If for some reason it is impossible to remove the figure() call, then it will be necessary to use findobj() to locate all of the plots on all of the figures and merge them into a single plot.

I got it working right before I saw your answer. Thank you though!

When plotting recursively it is often practical to use 'hold all' rather than 'hold on'. Include that before plotting the functions and the plots should end up in the same graph.
