P = [1 2]*10^7; % made up data to test with
S = [1 2;
2 3];
T = [0 70;
0 100];
plot(S(1,:),T(1,:), S(2,:), T(2,:))
grid on
ylim([0 130])
xlim([0 4])
for i=1:length(P)
% text(S(i,end), T(end), sprintf('%1.1f MPa', P(i)/10^6, 'Rotation',90))
% ^ ^
% move the paren at the end to here ^---------------| paren to here
text(S(i,end), T(i,end), sprintf('%1.1f MPa', P(i)/10^6), 'Rotation',90)
% ^ also index T
