Categs

Declaration:

TSpCollItem.Categs[catix: integer]: string;

The array property Categs allows to access the categories of a spectral collection item (see the section Definition of Categories for more). Please note that the categories are always stored as strings, even if a category is of a numeric or logic type. For tri-state values the allowed strings are "TRUE", "FALSE" and "" (empty string, if undefined). Hint: Please note that the categories must be defined before they can be used by setting the properties NumCategs and CategProps.
