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

The array property ClassVisible determines whether any graphics items of the class cnum are displayed or not. 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 temporarily "switch off" parts of the data in a chart. Please note, that ClassVisible only affects the visibility of the data. Items which have been made invisible can be processed like any other visible items.

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