MATLAB: How can i normalize a plot

Question

figure 1 show the plot which i am getting.

figure 2 shows the actual (normalized) plot which i am trying to achieve.

please note that only y axis has been normalized and logarithmic scale on both axes has been used

Answer 1

divide by signals by maximum value of EtRe. Something like this

max_EtRe = max(Etre);
EtRe_ = EtRe/max_EtRe;
Etlm_ = Etlm/max_EtRe;
% plot EtRe_ and Etlm_
