BondLabelStyle

BondLabelStyle

is an option for MoleculePlot and MoleculePlot3D that specifies the style to use for bond labels.

Details

  • Any style specification as used in Style can be used as a setting for BondLabelStyle.
  • Typical settings include:
  • Automaticuse automatic setting
    styleuse style for all bonds
    {b1->style1,b2->style2,…}use stylei for bond bi
    {pattistylei,…}use stylei for edges matching the pattern patti
  • Color directives such as Red, as well as text specifications such as Bold or Small, can be given.
  • Giving the option setting BondLabelStyle->style is effectively equivalent to replacing the label-like elements of a formatting or related construct by Style[label,style].

Examples

Basic Examples  (3)

Set the style for all bond labels:

Wolfram Language code: MoleculePlot[Molecule["butane"], BondLabels -> "Hi", BondLabelStyle -> Directive[Red, Italic, 18]]

Specify the style for individual vertex labels:

Wolfram Language code: MoleculePlot[Molecule["butane"], BondLabels -> "Hi", BondLabelStyle -> {Bond[{1, 2}, "Single"] -> Directive[Red, Italic, 18], _ -> Directive[Blue, Bold, 18]}]

Specify the style for individual atom labels using a pattern:

Wolfram Language code: MoleculePlot[Molecule["benzaldehyde"], BondLabels -> "BondIndex", BondLabelStyle -> {Bond[{_, "O"}] -> Directive[Blue, Italic, 15], _ -> Directive[Red, Bold, 15]}]

Plot the molecule with labels in 3D:

Wolfram Language code: MoleculePlot3D[Molecule["tetraaminomethane"], BondLabels -> "BondIndex", BondLabelStyle -> {Bond[{_, "H"}] -> Directive[Blue, Italic, 15], _ -> Directive[Red, Bold, 15]}]
