NChartPointState Class Reference

Inherits from NSObject
Declared in NChartPointState.h

Overview

The NChartPointState class provides methods to store state of a point. The state of a point is a complex of parameters such as position, brush used etc. for a particular period for a particular point. Each chart point should have at least one state representing the data from the data source for this point, but it can have multiple states. This allows the animation of a chart through time, while each NChartPointState represents the state of the point in a particular time tick. The transition from one state to another is animated automatically by linear interpolation of parameters stored in the states.
