     - `hasaxes` (type: bool\|bool[3]) — default: `false`
-    - `ticks` (type: [number[], number[], string[]][3]) — array containing the ticks' information for, respectively, x, y and z axes. The ticks' information is an array of three elements: big ticks' coordinates, small ticks' coordinates, big ticks' labels. Default: `[]`

     - `ticks_style` (type: [color[3]](/mathics-threejs-backend/types/color)) — array containing the ticks' colors for, respectively, x, y and z axes. Default: `[[0, 0, 0], [0, 0, 0], [0, 0, 0]]` (all ticks are black)
