Example

// Style buffer 0 as a solid blue line with width 2
this.api.SetIndexStyle(0, TDrawStyle.LINE, TPenStyle.SOLID, 2, "#0000ff");

// Style buffer 1 as a dashed red line with width 1
this.api.SetIndexStyle(1, TDrawStyle.LINE, TPenStyle.DASH, 1, "#ff0000");

// Style buffer 2 as a histogram with green bars of width 3
this.api.SetIndexStyle(2, TDrawStyle.HISTOGRAM, TPenStyle.SOLID, 3, "#00ff00");

// Style buffer 3 as invisible (for calculation purposes only)
this.api.SetIndexStyle(
  3,
  TDrawStyle.NONE,
  TPenStyle.SOLID,
  1,
  "#000000",
