Interface IlvMarkerHint

public interface IlvMarkerHint

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

In order to associate a marker hint with a renderer, you must use a class that implements both the IlvDataRenderingHint and the IlvMarkerHint interfaces. You can refer to the documentation of IlvDataRenderingHint to know how hints can be associated with data points.

Note: Marker hints will only affect the drawing of renderers that use marker symbols (for example line, area, stair, scatter and bubble renderers).

Since:

JViews 5.5
