Description:

The default justification for atom labels.

In an Automatically-justified atom label, the atom is assumed to be associated with the first element in the label, reading from left to right. The rest of the label is positioned so that it best stays out of the way of any attached bonds, while trying to keep that first element at the atom's position. For atoms attached on the right end of a bond, this results in an atom label whose display is equivalent to Left, such as "CH3" or "OMe". For atoms attached on the left end of a bond, the atom label will be swapped, producing text such as "H3C" or "MeO". Accordingly, if you have an atom label that you know should always be displayed from left-to-right, you should definitely specify some justification other than Automatic.

This is an enumerated property. Acceptible values are shown in the following list:
Value CDXML Name Description
-1 Right Text is right justified
0 Left Text is left justified
1 Center Text is centered
2 Full Text is fully justified
3 Above Text is stacked above
4 Below Text is stacked below
5 Auto Text is automatically positioned
6 Best Text is positioned at creation-type in the alignment that best avoids any associated objects, but that alignment is fixed from that point onward

If this property is absent:

The value from the same property of a containing object will be used. That is, if this property is omitted from an object, but present for the Document, the Document's value will be used. If no value is found at all, ChemDraw will use the value from its last-used Style Sheet. If no information is found in the Style Sheet either, the text is automatically justified.
