The following code may be of help in displaying the raw data and model on the same plot.

clear;
close all;
t = [10 12 20 25 40 50];
tensileStr = [8 18 20 34 44 46];
tensileStrCalc = 2.94 + 0.952*t;
plot(t, tensileStr,'o', t, tensileStrCalc,'-'); 
xlabel('Time');
ylabel('Tensile str (TS, MPa)');
legend('Tensile str', 'Tensile Str Calculated', 'Location', 'southeast');
title('Tensile str vs Time plot');
