You mean multiple header lines in a text file? Are they a fixed number or variable?
Look at the optional argument 'headerlines' in
doc textread
doc textscan
for starters, if so...
As for plotting, it all depends on what the data are -- just a x and y or a surface or what.

SOTOO...
c=[]; % an empty array to collect data into
fmt=repmat('%f',1,4); % format string for the numeric data 4/record
fid=fopen('31oct97.txt','r'); % open the file, return file handle
while ~feof(fid) % begin loop until run out of data in file
c=[c;cell2mat(textscan(fid,fmt,187,'headerlines',24))]; % read a chunk/concat onto previous
end
NB: aircode, not tested but basic idea...salt to suit.

You forgot to attach your data file. I suggest you use the readtable() function with the 'HeaderLines' option. (Requires R2013b or later.)
