I have the same problem.

I want to draw timing arrow but without letter at the beginning and end of arrow as show in example :

{ signal: [

  { name: 'A', wave: '01........0....',  node: '.a........j' },

  { name: 'B', wave: '0.1.......0.1..',  node: '..b.......i' },

  { name: 'C', wave: '0..1....0...1..',  node: '...c....h..' },

  { name: 'D', wave: '0...1..0.....1.',  node: '....d..g...' },

  { name: 'E', wave: '0....10.......1',  node: '.....ef....' }

  ],

  edge: [

    'a~b t1', 'c-~a t2', 'c-~>d time 3', 'd~-e',

    'e~>f', 'f->g', 'g-~>h', 'h~>i some text', 'h~->j'

  ]

}
