Interface IlvDataRenderingHint

All Known Implementing Classes:

IlvDefaultDataRenderingHint, IlvGradientRenderingHint

public interface IlvDataRenderingHint

This interface lets you specify the rendering style that must be used to display a given data point.

Rendering hints can be specified either globally or individually:

• To associate a rendering hint with all the data points of a data set, use the IlvChartRenderer.setRenderingHint(IlvDataSet, IlvDataRenderingHint) method.
• To associate a rendering hint with a specific data point, use the IlvChartRenderer.setRenderingHint(IlvDataSet, int, IlvDataRenderingHint) method.
