I need to offset a Y axis so that my data is more clear. Below is an example of what I'm dealing with.

As you can see the black airfoil coordinates plot is vary distracting from the -Cp plot. How can I shift the right y axis down with out having to subtract my y/c coordinates by some constant, because I still need the trailing edge of the airfoil to be at (1,0).

%if true
figure
hold on;
yyaxis right;
plot(xc,yc,'black','LineWidth',2)
ylim([-.5,1.5]);
ylabel('y/c');
xlabel('x/c');
yyaxis left;
for k=1:21
plot(xa,-cp(1,:),'r')
plot(xa,-cp(6,:),'g')
plot(xa,-cp(11,:),'b')
plot(xa,-cp(16,:),'c')
plot(xa,-cp(21,:),'m')
end
ylim([-2,9]);
ylabel('-Cp');
legend('-5^o','0^o','5^o','10^o','15^o')
hold off;
end
my current code is above for my plots. thanks.
