Hi,
I'm extracting from different files some data that have ot plot on the same plot, I use a loop like
figure, hold on
for j=1:m
s=load(fileA{j});
t=load(fileB{j});
plot (t(:,1),t(:,2),'-r+')
end
I'd like to plot t(:,1),t(:,2) on figure 1, and for example t(:,1),t(:,3) on another figure. Is it possible to do it in the same loop?
thanks for your help

Yes. When you call the figure() command, call it with an input argument:
>> figure(1)
>> figure(2)
Then, before you do the particular plotting command, call figure() again, using the input argument that you want to plot to:
>> figure(1)
>> plot(1:10)
>> figure(2)
>> plot(2:11)
When the figure number already exists, it makes that figure current.
You might want to read "doc figure", "doc gcf", and "doc hold" to make sure you don't overwrite the plot that is already there in that figure.

Use this instead:
for j=1:m
s=load(fileA{j});
t=load(fileB{j});
for i=2:size(t,2)
figure(i),plot(t(:,1),t(:,i),'-r+')
hold on
end
end
hold off

Thanks for the idea, I wrote something like that to plot the two different files
for j=1:m
s=load(fileA{j});
t=load(fileB{j});
for i=2:size(t,2)
figure(i),plot(t(:,1),t(:,i),'-r+')
hold on
end
for k=2:size(s:2)
figure(i+k), plot(s(:,1),t(:,i),'-r+')
hold on
end
end
hold off

just get the handles from those axes and use them as first argument in the plot
figure
hax1=axes
figure
hax2=axes
plot (hax1,t(:,1),t(:,2),'-r+')
plot (hax2,t(:,1),t(:,3),'-r+')

This is elegant as it doesn't require the extra figure function call every time! For looping and making animations, this is a faster approach. Just hand plot the axes handle to plot on. Thanks for this answer!
