Class ChartModel

java.lang.Object

org.onosproject.ui.chart.ChartModel

public class ChartModel
extends Object

A simple model of time series chart data.

Note that this is not a full MVC type model; the expected usage pattern is to create an empty chart, add data points (by consulting the business model), and produce the list of data points which contain a label and a set of data values for all serials.
