Class: TRChart
Declaration: property AnnoClassVisible[cnum: byte]: boolean;

The array property AnnoClassVisible controls whether a certain class (specified by cnum) of annotation items is visible or invisible. By default, all annotation elements are visible. The parameter cnum may take any value between 0 and 254. The value of 255 is reserved as a place holder for all classes.

This property may be used to selectively "switch off" parts of the annotations in a chart.

Hint: Please note that the method AnnoClassVisible affects only the elements of the annotation container. The visibility of the elements of the data container can be controlled by ClassVisible.

Example: The statement RC1.AnnoClassVisible[5] := false; make all annotation elements which belong to class 5 of instance RC1 invisible.
