Forward wave already on line, +1 reflection at right, -1 at left

vx = [ 0 0 0 0 0 0 0 0 .5 1 1 1 1  1 1 1 1 1 1 1 0.5  ];
xlineani(0,1e6,0,vx,vx)
 

Initial voltage on line, no initial current, so wave head in both directions.

+1 reflection at right, -1 at left

vx = [ 0 0 0 0 0 0 0 0 .5 1 1 1 1  1 1 1 1 1 1 1 0.5  ];
xlineani(0,1e6,0,vx)
