Joining points from a scatter plot with a single line

Hi I have a code which collects data from different files and loads them as scatter points on one graph. I am looking to join these point together but as the data source is different for each point I am struggling. Below is the code that creates the scatter plot is there anything that can be added to join the points?

dinfo = dir();
dinfo(~[dinfo.isdir]) = [];                             %zap non-directories
dinfo( ismember({dinfo.name}, {'.', '..'}) ) = [];      %zap . and ..
nfold = length(dinfo);
vars = cell(nfold,1);
folders = {dinfo.name};
for K = 1 : nfold
   thisdir = folders{K};
   vars{K} = load( fullfile(thisdir, 'CR_vs_NF.mat'), 'Contact', 'O' );
   plothandles(K) = plot(vars{K}.O, vars{K}.Contact, 'x');
   hold all
 end
   legend(plothandles, folders);
   ylabel('Contact Ratio');
   xlabel('Jumping frequency/Beam Natural frequency');
savefig('Cr_vs_NF.fig'); 
clear;

I would create a 2-column matrix from both ‘vars{K}.O’ and ‘vars{K}.Contact’ in the loop, then sort them using sortrows by column 1. Then plot the sorted matrix.

You forgot to attach CR_vs_NF.mat, or even a screenshot of what plot you have so far. Attach a PNG screenshot ( NOT a .fig file) with the picture icon:

Are you simply looking to have a double for loop to plot a line between every point and every other point?

Unfortunately, this link you have provided is not helpful to this question. He has different groups of data points and would like them connected via lines at a later time.
