How to move the line on the signal’s charts ?

 
Hi,
I saw that signal providers changed the line on the chart (every months for example). How do they do that? I attach a picture of what I’m talking about 
Thank you !

They don't and can't change it. The line is the time that the signal is first connected to MQL5 signal service.
