Class LoadIntervalChartPlotter

java.lang.Object
  be.ac.ulg.montefiore.run.totem.chart.model.plotters.LoadIntervalChartPlotter

All Implemented Interfaces:

ChartPlotter

public class LoadIntervalChartPlotter
extends java.lang.Object
implements ChartPlotter

This class is used to build an interval graph. The interval 0-maxValue is divided in a number of disjoint sets (correponding to the nbInterval parameter. For each of these sets, a bar is represented. The height of the bar corresponds to the frequency of the data for the considerated set. If some values are superior to maxValue, an extra category is added.

A typical use of this chart is to represent the relative load of the links of a domain. X Axis represent the load categories (ex: 0%-33%, 33%-66%, 66%-100%). Y axis is the relative number of links that match the load category.
