how do i "re attach" string columns to data columns for identification?

when i input data, matlab always separates my string data( column headers and row id's) from the data it represents...i have been able to work around this because matlab keeps everything in place and it is easy to slap them back together outside of matlab... but i am working with data brushing and graphs, the databrushing retrieves the data values but not the row id...so how do i "link' my data with its original identifiers in Matlab???

If I understand you correctly, here is a small example:
x = rand(100,1);
y = rand(100,1);
names = char(randi(100,[100 3])+50); %random names
scatter(x,y);
%Do the brushing
%
% Brush your selection and then right-click, create variable, name it
% xbrush
%
[~,idx] = ismember(xbrush,[x y],'rows'); %locate them
names(idx) %extract names
