Hi! Question about mean curve in subplots

i have made a subplot (2,1,1) with emg for 5 reflexes in each subplot. Now i would like to make a new figure with subplots (2,1,1) with the average curve for the 5 five reflexes in each subplot.

Script:

clear close all clc files=ls('*.txt');

max_acc=zeros(10,1); index_max_acc=zeros(10,1); max_emg=zeros(10,1); index_max_emg=zeros(10,1); tid=zeros(10,1); differens=zeros(10,1);

for i=1:length(files(:,1)) data = ReadVerTxtData(files(i,:),4); [max_acc(i),index_max_acc(i)] = max(data(:,2)); [max_emg(i),index_max_emg(i)] = max(data(:,3)); differens(i)=index_max_emg(i)-index_max_acc(i); tid(i) = differens(i) * (data(2,1) - data(1,1)); tid(i) = tid(i) * 1000; hold on

    if i <= 5
        subplot(2,1,1)
        plot...
        (data( (index_max_acc(i,1) : index_max_acc(i,1)+500), 1) - data( index_max_acc(i,1) ), ...
        data((index_max_acc(i,1):index_max_acc(i,1)+500),3))
    else
        subplot(2,1,2)
        plot...
        (data( (index_max_acc(i,1) : index_max_acc(i,1)+50), 1) - data( index_max_acc(i,1) ), ...
        data((index_max_acc(i,1):index_max_acc(i,1)+50),3))

    end  
end

    subplot(2,1,1)
    ylabel('Spænding (mV)')
    subplot(2,1,2)
    ylabel('Spænding (mV')
    xlabel('Tid(s)')

I HAVE TRIED THIS:

figure subplot (2,1,1) meanplot(1) % how do i get the mean of the first plot in my subplot on figure 1?

The issue is with "meanplot" implementation. Ideally, if you are doing this:

figure, subplot(2,1,1), plot(1:10)

This should open a new figure and plot the graph on the first axes (subplot(2,1,1)). It is not clear from your code what "meanplot" does and what is the first argument ('1') to the meanplot.

One way you can consider to modify your meanplot definition is to pass the handle to the newly created figure and then modifying the 'XData' and 'YData' properties of the axes handles to the figure. This is efficient but complicated approach.

If I have a functioned defined like this:

function meanplot()

      plot(1:10)

end

And then I run the following code, I get two different figures with the subplots:

subplot(211), plot(1:10)
subplot(212), plot(5:15)
figure, subplot(211), meanplot
