Dear friends
Hope you all will be fine
i am simulating a fiber link and i need to get plot between BER and received power at photodetector with different fiber lengths.When i get BER vs received power plot for L=50km and when i change length from 50km to 80km,then the previous plot between BER vs power for L=50km vanishes and new one for L=80km comes.How to retain both curves on a single plot between BER and received powers for L=50 and 80Km????I mean to say how to do legends labeling????Please help
