package inet.visualizer.base;

//
// Base module for statistic visualizer simple modules. It keeps track
// of the last value of a statistic for multiple network nodes. The actual
// visualization of statistic values is done in derived modules. It subscribes
// for the signal determined by the `signalName` parameter at the module specified
// by the `visualizationSubjectModule` parameter. If the visualizer receives such a signal,
// it checks if the source matches the `sourceFilter` parameter. If the signal
// passes the check, it determines the last value of the statistic specified by
// the `statisticName` parameter.
//
// The format string can contain the following directives:
//  - %s: signal name
//  - %n: statistic name
//  - %v: statistic value
//  - %u: statistic unit
//
// @see ~StatisticCanvasVisualizer, ~StatisticOsgVisualizer, ~IStatisticVisualizer, ~VisualizerBase
