Interpolating graphs to match

Would I just use 1D interpolation to match up two graphs?

Yes very much possible. Check the below example.

% Generate two random graphs with different sizes 
y1 = rand(1,100) ; 
y2 = rand(1,70) ; 
% lengths of each graph 
n1 = length(y1) ; 
n2 = length(y2) ; 
% get y2 to size of y1 
x2 = 1:n2 ; 
xi2 = linspace(1,n2,n1) ; 
% interpolate y2 to size of y1
yii = interp1(x2,y2,xi2) ;
