|Home ChartPack RChart Class TContourPlot Properties ClassVisible|
|See also: Class numbers, AnnoClassVisible, ClassDefault|
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.
