Interface IRangePolicy

All Superinterfaces:
Serializable
All Known Implementing Classes:
ARangePolicy, RangePolicyFixedViewport, RangePolicyForcedPoint, RangePolicyHighestValues, RangePolicyHighestValuesForcedMin, RangePolicyMinimumViewport, RangePolicyUnbounded
public interface IRangePolicy extends Serializable
An interface that allows an axis to be plugged with a range policy.

Implementations may limit the range of the underlying Chart2D's data (clipping / zooming), increase it (void space offset), guarantee a minimum viewport... .
