How can I plot a figure with 5 subplots and save it and then move to the next figure containing 5 subplots and save it under an other name?

Hy, I have a dataset of 100 columns (each columns represents one channel) 150000 rows.

Now I want to create 20 figures and each figure should show the data of 5 channels in subplots.

For example:

for i=1:5
   h(i) = subplot(5,1,i);
    plot(t,Ch0_99_OS1(:,i));
    title(NewName(i));
     ylabel('intensity [a. u.]');
      xlabel('time [sec]');
      ylim ([-1200 27000]);
end

Now I want to save the file as Ch1_5.png and start with the next figure containing the data from channel 6-10.

How can i do this?

Thanks

You can assign a figure number with the figure command.

You can save a figure with the savefig command.

Just put them both, or the savefig, into a for loop and you should be good.

for f = 1:20;
    for i=1:5
       h(i) = subplot(5,1,i);
       plot(t,Ch0_99_OS1(:,i+(j-1)*5));
       title(NewName(i));
       ylabel('intensity [a. u.]');
       xlabel('time [sec]');
       ylim ([-1200 27000]);
    end
    savefig(['myfigure',num2str(f),'.png']);
end
