Here is a portion of code I use to read multiple files in cases like this:
for r=1:6 % Number of files
myfilename= sprintf('%i.data',r); %file names as 1.data, 2.data and so on.
filename = fullfile('C:\','Users','User','MATLAB',myfilename); % Put your file path here
fid = fopen(filename,'r'); % Open the file
Mydata = textscan(fid,'%f %f');% Assuming you have 2 columns of floating point data. Update as per your file accordingly.
fid = fclose(fid); % CLose the file
%%Delete temporary variables from workspace
%%Process the data
%%Plot the data
end
Hope this helps!!

I don't think you need eval for this. Try something like this:
for r=1:6 % Number of files
myfilename= sprintf('%i.data',r); %file names as 1.data, 2.data and so on.
filename = fullfile('C:\','Users','User','MATLAB',myfilename); % Put your file path here
fid = fopen(filename,'r'); % Open the file
Mydata = textscan(fid,'%f %f');% Assuming you have 2 columns of floating point data. Update as per your file accordingly.
fid = fclose(fid); % CLose the file
%%Delete temporary variables from workspace
%%Process the data
%%Plot the data
figure(r) % this will give you a new figure for each set of data
plot(x,y) % Put your data here
file_name=sprintf('%d',r)
hgsave(file_name)
end
