'_chemical_conn_atom_display_x' '_chemical_conn_atom_display_y'

Category: chemical_conn_atom

Data type: numb

Must appear in a looped list containing '_chemical_conn_atom_type_symbol'

Enumeration range: 0.0 -> 1.0


   The 2D Cartesian coordinates (x,y) of the position of this atom
   in a recognisable chemical diagram. The coordinate origin is at
   the lower left corner, the x axis is horizontal and the y axis is
   vertical. The coordinates must lie in the range 0.0 to 1.0. These
   coordinates can be obtained from projections of a suitable
   uncluttered view of the molecular structure. If absent, values
   will be assigned by the journal or database staff.
