How can i make smooth lines its start and end like above picture ?

Those lines are neatly anti-aliased, which the LineRenderer doesn’t do out of the box (unless you have other antialising mechanics in place in your application).

In general though, the LineRenderer doesn’t do screen space graphing very well. It exists solely in 3D and also billboards the individual line segments towards the camera, which can disturb the feeling of a uniform line width.

You should consider buying Eric’s Vectrosity plugin for doing line rendering in screen space. It’s extremely efficient, very well documented, easy to use, and very cheap for what you get:
