Unit: SDL_rchart
Class: TRChart
Declaration: function LoadAnno (FName: string; AppendIt: boolean): integer;

The method LoadAnno loads the annotation container of a TRChart instance from a file with filename FName which has been created by a previous call to SaveAnno. The parameter AppendIt determines whether the loaded annotation items are appended to the existing ones, or the annotation container is cleared before loading the items.

The function returns the following result:

≥0 ... everything is OK, the returned value specifies the number of annotation items read from the file
-1 ... the file cannot be read
-2 ... the file is not an annotation file (missing version and annotation id)
