What happened to Line Renderer!

I have been following this video tutorial on youtube, and the video has been made 2 years ago. We eventually got to the Line Renderer component, and I notice some things were missing(By the way I have Unity5.6.1). So eventually in this tutorial, I need to change the value of both the Start Width and End Width, also I need to change the Color of the Start Color and End Color, but I couldn’t find where it was. Where is it, and if It isn’t there how can I set the Line Renderer Start Width/End Width and Start Color/End Color in c#.

Video Tutorial’s Line Renderer:

My Line Renderer:

The graph below Width determines the width along your line renderer, and the color field actually accepts a gradient, which you can set if you click on that field.
