Information entered to the command window:
>> x=0:1.96:19.62; y=[0,1,3,11,25,38,52,66,78,93,106];
>> plot(x,y,'+')
>> xlabel('Load/N'); ylabel('Deflection/mm'); title('Measuring the Stiffness of the Spring');
The Figure plotted using the basic fitting linear option:
However I want my best fit line to go through the origin (0,0) without altering the data values or the scale of the axis.

You want to find the slope a of the line
In Matlab you can use the backslash operator to do this, after transposing your arrays to column vectors:
a = x'\y';
plot(x,y,'*',x,a*x)
