Freeze areas and visible report areas
The display of objects in reports can be affected by adjacent objects. For example, the space between a chart and its legend may widen and narrow when you drill up and down through the data displayed in an adjacent hyperblock.
To prevent this you can define a freeze area. Objects within a freeze area do not expand.
You can also specify that only part of a report is visible. This can be used, for example, to hide data and calculations on which the report is based.
Note: A visible report area must include cell A1.
