How can I plot average loop graph as given in the image

clc
clear all
close all
C = readtable('A_G1.txt', 'NumHeaderLines',8);
%Convert to SI Units
accG2test = C{:,1}.*9.81;
forceG2test = C{:,2}.*0.00981;
dispG2test = C{:,3}./1000;
dispG2test2 = smoothdata(dispG2test, 'sgolay', 100);
%force
forceG2test2 = smoothdata(forceG2test, 'sgolay', 100);
z = linspace(min(dispG2test2),max(dispG2test2),length(dispG2test2));
[cmin,cxix] = (min(dispG2test2));
[cmax,cnix] = (max(dispG2test2));
[fmin,fxix] = (min(forceG2test2));
[fmax,fnix] = (max(forceG2test2));
%meana = mean(dispG2test2,3);
%meanb = mean(forceG2test2,2);
%xx = spline(meana,meanb);
figure(1)
plot(dispG2test2, forceG2test2)
hold on
plot([cmin cmax], [fmin fmax], '+r', 'MarkerSize', 5, 'LineWidth',1.5)
%plot (xx,'or')
hold off
legend('Force v. Deflection');
title('Force vs Deflection');
xlabel('Deflection[m]');
ylabel('Force[N]');

I'd start by looking at splitapply(), grpstats(), or groupsummary() to get the average of each unique pair of (x,y) coordinates.

If you're going to cross verify (compare mine to yours) then that means you already have your own version already. Tell me your way first.

yes i tried using the mean as I have commented in the code. But it didn't work so i was trying but i am not able to do it. So was asking for your help.
