You could achieve something like that using a subplot.

Use AXES to create a new axis relative to the another axes

x = 0:100 ; y = exp((x/50).^2)+rand(size(x)) ; % some data
% plot #1
ph = plot(x,y,'b-')
hold on 
fill(x([1 1 50 50]),y(1) + [1 -1 -1 1],[1 1 0]) 
hold off ;
uistack(ph,'top') 

% insert plot
p0 = get(gca,'position')
p1 = [p0(1)+0.1 p0(2)+0.3 p0(3)/2 p0(4)/2]
axes('Position',p1)
plot(x(1:50),y(1:50),'b-')
