%% input data
P1=[2.3;3.9;3.5;4.8;5.5;6.3;7.4];
P2=[4.8;5.7;6.5;7.8;9.2;10.5;11.8];
D=[78;65;57;52;46;32;27];
%%
Dp=P2-P1;
Q=0.24*D;
%% plot
subplot(3,1,1);plot(Dp,'r*');grid on;axis tight;
subplot(3,1,2);plot(Q,'b*');grid on;axis tight;
subplot(3,1,3);plot(Dp,'r*');hold on;plot(Q,'b*');hold off;grid on;axis tight;legend('Dp','Q');
How do i plot a curve between Dp and Q ? in the third subplot

D=[78;65;57;52;46;32;27];
%%
Dp=P2-P1;
Q=0.24*D;
%
x = [1:length(Dp) flip(1:length(Q))] ;
y = [Dp; flip(Q)] ;
plot(x,y)

Do you mean Dp vs Q?
