Interface IlvDataRangePolicy

All Known Implementing Classes:

IlvDefaultDataRangePolicy

public interface IlvDataRangePolicy

Defines a strategy for calculating the data range of chart axis.

The IlvChart class uses an IlvDataRangePolicy object to compute the data range of its axis.

Since:

JViews 5.0

Method Summary

Modifier and Type	Method and Description
IlvDataInterval	computeDataRange(IlvChart chart, IlvAxis axis, IlvDataInterval retRange) Computes the data range of the specified chart axis.

Method Detail

computeDataRange

IlvDataInterval computeDataRange(IlvChart chart,
                                 IlvAxis axis,
                                 IlvDataInterval retRange)

Computes the data range of the specified chart axis.

Parameters:

chart - The considered chart.

axis - The considered axis.

retRange - An interval used to store the result. If this parameter is null, a new IlvDataInterval must be allocated.

Returns:

The computed range. This range can be empty (for example if no data is projected along the specified axis).
