Hi
For a purpose, I am trying to have a just specific part of my plot only. For example, if you run the below code, you will get figre 1 (attached file), but I want have just part of it that has been shown in figure 2 (attached file). I dont mean about using axis function (axis([0,18000,0,2000]);). I want to eliminate other part of the plot after plotting.
Thank you in advance for you help.
Regards,
Shahin
