All Implemented Interfaces:

HasDataset

Direct Known Subclasses:

GaugeDataset

public class MeterDataset
extends Dataset

The Meter chart allows a number of properties to be specified for each dataset. These are used to set display properties for a specific dataset.
The minimum value of data is 0 (see MINIMUM_VALUE).
The dataset will have always 2 data and setting the color of data, the first is the value color and the second is the empty one.
To set the data, is mandatory to use setValue(double)) method.
